That's copper acetate. Copper is Cu, and the acetate polyatomic ion is C2H3O2, although copper's most common valence state is +2, so the more likely formula would be Cu(C2H3O2)2. (acetate has a -1 charge.)
Yes, copper acetate is a salt.
Yes -- salt and vinegar react to form sodium acetate and hydrochloric acid. NaCl + CH3COOH --> NaCH3COO + HCl
When copper reacts with acetic acid, copper acetate is formed. Copper acetate is a dark greenish-blue colour.
Copper(II) Acetate
A: Jaydeep Tubes' copper nickel tubes offer exceptional corrosion resistance, durability, and thermal conductivity, making them ideal for various critical applications.
ketchup - the vinegar ( acetic acid ) in ketchup changes the copper oxide to copper acetate which is soluable in water.

Yes, copper acetate is a salt.
Yes, the copper(II) acetate is a copper salt.
There is acid called ACETIC ACID it combines with the copper to form a copper acetate(the green coating on the pennies)!!!!!!!!!!!!!!!!!! coiol huh

Half-reactionsSince 1982 US cents have been made of zinc plated with a thin layer of copper. It took the Mint several years to stabilize the plating process to prevent reactions when the coins were exposed to air, dirt, skin oils, and such. Many early-date zinc cents exhibit black spotting and mottling because of those problems. Vinegar ReactionIdeas suggests that the acetic acid in vinegar reacts with the copper oxide that has formed on older pennies, and the resulting byproduct is copper acetate. The copper acetate then dissolves in the vinegar solution, therefore getting rid of the black color-producing agents and making it a bit shinier, although it will not appear as shiny as it once was with just vinegar.Vinegar and Salt ReactionThe vinegar in this solution does its job and removes the copper oxide, thus getting rid of the black color. If you place the pennies in the salt and vinegar solution, then take them out without rinsing them, the surface will turn greenish if given ample time to do so. This reaction may become apparent within a few hours or up to a week. Science Project Ideas calls this reaction verdigris; this name can reference many different copper compound reactions, including the one that the salt and vinegar mixture produces. Copper chloride is the name of the chemical reaction of mixing the copper and the sodium chloride from the salt. Copper acetate is the name for the reaction of the copper and acetic acid in vinegar. To prevent this copper reaction, just rinse the pennies after you take them out of the solution
Copper(II) Acetate
Copper (II) acetate has the chemical formula Cu(CH3COO)2.It is the primary component of verdigris, the green patina seen on copper statues.
Pennies are made of zinc plated with copper. Copper reacts with oxygen and water to form copper oxide. This is the tarnish you see on pennies that have been in damp conditions. The only U.S. coins that can truly rust are the 1943 zinc coated steel cents.
