What does electrolysis of saltwater make?

If "salt" is Sodium Chloride, then you will be making Hydrogen gas (H2) and (Oxygen gas (O2) and/or Chlorine gas (Cl2)).\n\nUnless you plan on very carefully controlling the potential difference across your electrolytic cell to use just the bare minimum voltage, you are likely to make Chlorine gas at the anode instead of Oxygen.\nOxygen gas has a reduction potential of 1.23 volts, where are Chlorine gas has a reduction potential of 1.36 volts.\nThis means that if you supply just a tiny bit of extra voltage across the cell, instead of just producing Oxygen gas from the water, you will be oxidizing the Chloride ions in solution to make Chlorine gas.

There are many ways to generate hydrogen outside electrolysis. Steam reforming, methane reforming, propane reforming, etc... Coastal countries may appear to have an advantage but you cannot have a fair comparison of supply and demand.  Consider the following:\n1. Many, many, many countries have access to coastal water, thus competition would be extremely fierce\n2. Countries will be more than self-sufficient and may "sell" excess product at a very low cost.\n3. Rivers, streams, rainwater etc... is available to more countries in the world than petroleum to many. \n \nI would not worry about it, depleting the sea is way way way way off, and besides, using H2 as fuel means that emission is....water. And no, the roads are not going to be slippery from algae (sorry, but I have heard a statement like that in the past)\n\nEver considered that we may come up with the technology to recover and re-use the water emission? Thus less filling up at your local Shell H2 station? \n\nI hope I was able to answer it for you in a objective manner

Electrolysis of water causes the formation of hydrogen peroxide with the result of rapid redox reactions that would cause gel to run way too fast. Also, while water can conduct electricity, it  heats up when electrified. Depending on the voltage, the water can get hot enough to melt the gel.

Pure water is *not* a good conductor of electricity.  Dissolved ions are necessary to conduct electricity and at room temperature, there is only 10^-7 mol/L of H+ and OH- in pure water.\n\nDissolving salts (including strong acids) in water greatly increases the conductivity of the solution.\n\nTap water is a modest conductor of electricity because of dissolved ionic minerals and impurities.\n\nHeating water increases its dissociation constant making more H+ and OH- available in solution.

Process Electrolysis\n\nYou will need two ordinary glasses, A pan , a DC electrical source and some supports to support the glasses in the pan with the rim below the water level.\n\nYou can find a simple experiment  and details here : http://en.wikipedia.org/wiki/Electrolysis

It is just the equalizing of electrical charge between two people or a person and a conductive object.\n\nFor example, if your dragging your feet on the carpet, you are building up a greater negative electrical charge on your body.  When you come in contact with someone who has less negative charge than you, nature tries to make everything equal by sharing some of your negative charge.  \n\nSimilar concept if you add saltwater to pure water, the mix shares the salt with the "less salty" water.  Now the pure water is more salty, but the salt water is less salty than it was.  Hope this helps.\n\nThe link below is a bit more complex, but explains the underlying priciples.

Everyone who has been to the beach knows that seawater is salty. Everyone also knows that fresh water in rain, rivers, and even ice is not salty. Why are some of Earth’s waters salty and others not? There are two clues that give us the answer. First, “fresh” water is not entirely free of dissolved salt. Even rainwater has traces of substances dissolved in it that were picked up during passage through the atmosphere. Much of this material that “washes out” of the atmosphere today is pollution, but there are also natural substances present.\n\nAs rainwater passes through soil and percolates through rocks, it dissolves some of the minerals, a process called weathering. This is the water we drink, and of course, we cannot taste the salt because its concentration is too low. Eventually, this water with its small load of dissolved minerals or salts reaches a stream and flows into lakes and the ocean. The annual addition of dissolved salts by rivers is only a tiny fraction of the total salt in the ocean. The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years.\n\nA second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the world’s lakes are not? Lakes are temporary storage areas for water. Rivers and streams bring water to the lakes, and other rivers carry water out of lakes. Thus, lakes are really only wide depressions in a river channel that have filled with water. Water flows in one end and out the other. \n\nThe Great Salt Lake, Dead Sea, and other salt lakes have no outlets. All the water that flows into these lakes escapes only by evaporation. When water evaporates, the dissolved salts are left behind. So a few lakes are salty because rivers carried salts to the lakes, the water in the lakes evaporated and the salts were left behind. After years and years of river inflow and evaporation, the salt content of the lake water built up to the present levels. The same process made the seas salty. Rivers carry dissolved salts to the ocean. Water evaporates from the oceans to fall again as rain and to feed the rivers, but the salts remain in the ocean. Because of the huge volume of the oceans, hundreds of millions of years of river input were required for the salt content to build to its present level.\n\nRivers are not the only source of dissolved salts. About twenty years ago, features on the crest of oceanic ridges were discovered that modified our view on how the sea became salty. These features, known as hydrothermal vents, represent places on the ocean floor where sea water that has seeped into the rocks of the oceanic crust, has become hotter, and has dissolved some of the minerals from the crust, now flows back into the ocean. With the hot water comes a large complement of dissolved minerals. Estimates of the amount of hydrothermal fluids now flowing from these vents indicate that the entire volume of the oceans could seep through the oceanic crust in about 10 million years. Thus, this process has a very important effect on salinity. The reactions between seawater and oceanic basalt, the rock of ocean crust, are not one-way, however; some of the dissolved salts react with the rock and are removed from the water.\n\nA final process that provides salts to the oceans is submarine volcanism, the eruption of volcanoes under water. This is similar to the previous process in that seawater is reacting with hot rock and dissolving some of the mineral constituents.\n\nWill the oceans continue to become saltier? Not likely. In fact the sea has had about the same salt content for many hundred of millions if not billions of years. The salt content has reached a steady state. Dissolved salts are being removed from seawater to form new minerals at the bottom of the ocean as fast as rivers and hydrothermal processes are

This is different for the different halogens. Chlorine is obtained by electrolysis of sea-water, but bromine and iodine can be obtained by using the differences in reactivity between them and chlorine.  Look them up as "extraction of chlorine" and "extraction of bromine" (and so on) and you'll get the answers.

If you ferment the biomass it will make methane. The remove the hydrogen from the methane? If you meant seawater, electrolysis will give you hydrogen and oxygen. A lot was manufactored in Norway since they had hydroelectricity to use.

If you get into folk stories and mythology you will see that almost every culture has a story explaining how the oceans became salty. The answer is really very simple. Salt in the ocean comes from rocks on land. Here's how it works:\n\nThe rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water). The rain erodes the rock and the acid breaks down the rocks and carries it along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers to the ocean. Many of the dissolved ions are used by organisms in the ocean and are removed from the water. Others are not used up and are left for long periods of time where their concentrations increase over time.\n\nThe two ions that are present most often in seawater are are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. By the way, the concentration of salt in seawater (salinity) is about 35 parts per thousand. In other words, about 35 of 1,000 (3.5%) of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater the weight of the salt, as sodium chloride, would be about 120 million tons. And, just so you don't think seawater is worthless, a cubic mile of it also can contain up to 25 tons of gold and up to 45 tons of silver! Before you go out and try alchemy on seawater, though, just think about how big a cubic mile is.\n\nBy some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 m) thick, about the height of a 40-story office building.

Electrolysis. Running a current through water will separate it into hydrogen and oxygen.

One way to do that for relatively small volumes of water is to force the sea water through a special membrane filter under high pressure. The filter membrane must be constructed so that its holes are large enough to just pass a water molecule, but not large enough to pass metal\nmolecules, salt molecules, algae, etc. The result would be fresh clean water with a lot of brine solution left in the pressurized tank that needs to be dumped.\n\nAnother process which is more poractical for large volumes of fresh water production is electrolisis. In that process, electrical current is passed through the water to break it down into its basic elements such as hydrogen and oxygen (and all the other junk that is left over).\n\nOnce the hydrogen and oxygen are collected and recombined, the result is pure fresh water. Again, the vat or tank holding the original sea water now has a heavy brine solution which must be disposed of somehow. Most any use of sea water to produce fresh water will generate a lot of salty brine by-product that could poison sweet earth in the vicinity if it is merely dumped.

Another name for the electrolytic dissociation of sodium chloride solution is electrolysis of brine.\n\nThe electrolysis would generate hydrogen gas, chlorine gas, and a solution of sodium hydroxide.

Yes, salt water is a sodium chloride solution with Na+ and Cl- ions. when two seperate condutors are immersed in the solution without contacting each other and a bulb or any electrical appliance is placed across the conductors the positive and negative ions migrate and conducts electricity.

I will make NaOH from the electrolysis of brine(saturated NaCl solution) using graphite anode and mercury cathode. On electrolysis, sodium will combine with mercury to form sodium amalgam(Na/Hg). Then make that sodium amalgam to combine with water(H20) so that we can get NaOH.
