What is precipitation of dissolved material?

it is when a material is caused to drop out of solution, think about a salt water solution and then you make the salt to come out of the solution. i could give you a chemial reaction equation for a different example, but just imagine that you dissolved salt into water (any solution) and then you wanted to make that salt come back out of the water again. you could add another chemical to make that happen, and when you did, the salt would drop out of the water along with whatever chemical you added to make the reaction occur.  hope that helps!

Are you talking molecular level or physical process?\n\nWater is the bond between Hydrogen+ and two Oxygen- formulating H2O.\n\nWater as in the rain.  Evaporation is the water droplets from the sun heating up the water rising to the sky, also the plants perspire its water from the heating of the sun and rises to the sky, then condensation is the cooling of the droplets and condensing, weighs down the cloud with concentrated & heavier droplets and precipitation is the actually rain droplets falling to Earth.\n\nThe chemical process of cleaning the water to drink is the earthly cycle, but you want to go with human cleaning is the introduction of a sanitizing and killing bacteria in the water with chlorine and making it supposedly healthy with fluoride.  And a bunch of supposed microfilters to catch debris and bacteria.  Heating the water also helps clean it a little.

An acid is a substance which is capable of forming hydrogen ions when dissolved in water.

Well water can over time through a process called weathering, other than that acid is excellent, that is how acid rain is effecting us.\nAlso salt and a number of other chemicals and solvents.

Acidic rainfall dissolves soluble rock, such as limestone.\n\nThis article has some examples and pictures of Karst topography:  http://en.wikipedia.org/wiki/Karst

syrup is a solution, it is clear and has much sugar dissolved.\nmilk is not a solution, it is not clear, particles are too big\neye drops are solutions, clear\ntomatoe juice is not, not clear\ntap water is, many minerals dissolved

Water contains many dissolved ions, chief among them being Calcium and Magnesium. At high levels of alkalinity, event the CO2 present in the atmosphere or released from washing soda reacts with Ca2+ to give rise to CaCO3 and hence the milky appearance.

The precipitate is a solid, and it usually is in the form of a salt (i.e. NaCl)  If you are given an equation that begins with two liquids, for example, and one of the end products is solid (s), then you know that that is a precipitate.  \n\nPrecipitation can occur for a few different reasons.  One reason can be due to the insolubily of one of the reactants and wil result in precipitation  This can also be due to supersaturation of the mixture that causes the insoluble material to precipitate out of solution.\n\nWikipedia has a nice example using Silver Chloride (AgCl).

Rain and sun promote chemical reactions, leaching material out of the poop. What are left are the chemicals that do not dissolve in water - mostly potassium nitrate. This is one of the ingredients for making gun powder and, in days gone by, manure was an important resource for the military!

b a solution, the salt will dissolve

Ionic precipitation is when two ions say Ba+2 and a S-2 get together and precipitate into BaS2 (ppt) which in insoluble. Which is different if two organic molecules react to form an insoluble substance.

Evaporites are minerals dissolved in seawater (or freshwater) that are deposited in a certain sequence, when and if the water evaporates to the point where the minerals become insoluble.\n\nSince I figure this is a HW question, I'll only give you a hint for the second part of the question:  think "Gulf of Mexico."

"Cloud Condensation Nuclei"\n\nThese are the suspended particles that water condenses around in order to form a rain drop. It may be dust, smoke, salt, or any other solid that is in aerosol form in the atmosphere.

Probably to determine the amount of dissolved solids (commonly called "Total Dissolved Solids" or "TDS") in it.  Dissolved solids are anything dissolved in the water that will leave a residue when evaporating it to dryness.  \n\nIn this case it will consist primarily of sugar, except for the diet, which will have no sugar.\n\nMore about TDS:  The reason you can detect the density difference between pure water and sugar water, is that most solids will have a higher density than water.  Therefore, when they are mixed or dissolved in the water, they will increase the density.

First off... dihydrogen monoxide is ....WATER!!!!!!!!!\n\nThe smaller the salt crystals you are trying to dissolve, the more rapidly they will dissolve... due to increased surface area.

mostly mineral, you'll probably find sodium chloride (salt) in it, but it depends on which water body is evaporated.
