What is a pickle solution made of?  Are there different types? (soldering pickle)?

Look here:\n\nhttp://jewelrymaking.about.com/od/solderinginformation/a/032806.htm\n\nand here:\n\nhttp://alchemy.chem.uwm.edu/amalgamator/NCW/ncw2001/results.html\n\nto get the following:\n\nThe pickle, used in the soldering metal process is a sodium bisulfate based solution. This pickle is particularly good for gold. Other metals use different pickles. For example, "Copper and copper alloys can be pickled in sulfuric acid solutions with the addition of an oxidizing agent (for heavy scales) such as chromic acid, nitric acid, ferric sulfate or sodium dichromate. NOTE: Chromic acid and dichromate require treatment for hexavalent chromium. Chromic acid or dichromate solutions tend to passivate the substrate and require activation prior to plating. Activation is commonly carried out in 5-10% sulfuric acid solution or 10-20% hydrochloric acid solution. If the latter is used to interchangeably pickle steel parts and copper parts, the dissolved copper must be closely controlled to avoid a typical problem. The dissolved copper will eventually plate out on the steel parts and cause adhesion problems."\n\nI hope this helps.  Be careful.

A fluid is a material that flows, such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent.\n\nSome solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine. A sterilized specific concentration (0.15 molar) of sodium chloride in water is called saline. A solution of carbon dioxide in water is called seltzer, and a solution of ammonia gas in water is called ammonia water.\n\nA solution is said to be dilute if there is less of the solute. The process of adding more solvent to a solution or removing some of the solute is called diluting. A solution is said to be concentrated if it has more solute. The process of adding more solute or removing some of the solvent is called concentrating. The concentration of a solution is some measurement of how much solute there is in the solution.\n\nIt might initially offend your sensibilities to consider a solution in which the solvent is a gas or a solid. The molecules of a gas do not have much interaction among them, and so do not participate to a large extent in the dissolving process. Solids are difficult to consider as solvents because there is a lack of motion of the particles of a solid relative to each other. There are, however, some good reasons to view some mixtures of these types as solutions. The molecules of a gas do knock against each other, and the motion of a gas can assist in vaporizing material from a liquid or solid state. The fan in a 'frost free' home freezer moves air around inside the freezer to sublimate any exposed ice directly into water vapor, a process clearly akin to dissolving. Solid metals can absorb hydrogen gas in a mixing process in which the metal clearly provides the structure.\n\nTrue solutions with liquid solvents have the following properties:\n\nPROPERTIES OF SOLUTIONS\n\n   1. The particles of solute are the size of individual small molecules or individual small ions. One nanometer is about the maximum diameter for a solute particle.\n   2. The mixture does not separate on standing. In a gravity environment the solution will not come apart due to any difference in density of the materials in the solution.\n   3. The mixture does not separate by common fiber filter. The entire solution will pass through the filter.\n   4. Once it is completely mixed, the mixture is homogeneous. If you take a sample of the solution from any point in the solution, the proportions of the materials will be the same.\n   5. The mixture appears clear rather than cloudy. It may have some color to it, but it seems to be transparent otherwise. The mixture shows no Tyndall effect. Light is not scattered by the solution. If you shine a light into the solution, the pathway of the light through the solution is not revealed to an observer out of the pathway.\n   6. The solute is completely dissolved into the solvent up to a point characteristic of the solvent, solute, and temperature. At a saturation point the solvent no longer can dissolve any more of the solute. If there is a saturation point, th

There are all sorts of salts:\nacid + base = salt + water\nHCl + NaOH = NaCl + H2O\n\nNaCl is sodium chloride. This is the same stuff we use at the table. If you have a look at the packet it came in you will probably find there are a few other things in the 'table salt' too - perhaps some iodides and an anti-caking agent to keep it running freely.\n\nMore info. on 'table salts':

glue, lots of glue. I had to build a mini-bridge out of toothpicks for a school project to see how much weight it held, and I covered it in glue and it almost won, but another kid cheated and used dow rods and he won, but by very little.

Googling around to equipment manufacturers, what I'm finding makes it look like they are heat sealed, so I'm assuming that it has to be a melting glue. It also has to be non-toxic since it is a food product.\n\nThe site below has fill-your-own bags that are pre-glued and sealed with and iron.

Since the questin was posted as chemistry I shall give you a chemical example:\nWhen you store pickles, you never do so in a metal container [particularly aluminium], rather we use "stone jars". This instills an intuition in you that something happens between the pickle and Al.\nIndeed, the tartaric acid present in the pickle reacts with Al giving Al-salt [tartarate] which is toxic in nature.

Well, you'd have to specify what you are trying to dissolve.  Many plastics are soluble in several solvents... N-Methylpyrrolidone being a good one.  Solvents generally do not attack metals, unless they contain water.  I would steer away from an acid or a base.  Can you say what you're thinking of?  If so, email me at connecticutpoet37@yahoo.com

The soldering iron must have an insulated handle so that you can manipulate it without getting burned.  It also has a hot tip to heat the surfaces to be soldered so that the solder will melt and flow where it is needed.  Usually flux is applied to the surfaces to help the solder "wet" the surfaces rather than bead up and fall off.  Early soldering iron tips were heated in a flame and were relatively massive to hold more heat.  Now, electric soldering irons are used and can be much lighter because they have a constant supply of heat from an electric heating element.  The copper tips may also have two electrical connectors that allow electric current to pass through the tip and heat it due to resistance.  The tips are often made of copper (not iron) because it is a very good heat conductor allowing it to heat quickly and readily transfer heat to the work.  It is often necessary to sandpaper the tip to expose fresh copper and obtain the best heat transfer possible.

Could you use lead solder?

A solution cannot have a structure unless it is frozen solid. Starch will be present in the hemiacetal form in it.

more soluble in what solution?

My friend did one that answered the question : "Which melts ice faster: Salt or spices?"\n\nShe experimented with salt and spices like cinnimon, peprika, chili powder, red pepper...\n\nIt was pretty cool. The title we came up with was "Salt or Spice Melts the Ice?" \n\nSalt melted it the fastest.

i dont know if a mole is the HEART of chemistry, but it is important for relating things from the molecular level to the measureable level\n\na pencil is not just one element, it is usually made of wood, metal, rubber, and graphite \n\nif you were asking what is the graphite (commonly called lead) is made of, it is carbon.  atoms of carbon make up molecules of graphite

soldering what? pipe or wire

Please, the question is not completed because if you are try to use separating techniques , you must have a mixture that you want to separate so toothpick is just a substance and not a mixture you can add any other substance before it become a mixture.\nthanks for my mark.

A standard faucet is made of nickel and chrome plated brass. Lamp parts are made of brass. Standard flatware is made of 18/8 stainless steel, which is 18%chrome and 8%nickel. any rass items are made of Copper and zinc. Bronze items are made with copper and tin. Household wiring obviously is made of 99.9% copper. Some mixing bowls are made of copper.(Great for making meringue). Nickel by itself is WAY to expensive so there are not many things out there that are made entirely of nickel. Circuit boards are made of tin coated copper. Be imaginitve...  :-)
