What chemical will restore dates to copper coins and pennies?
You're probably looking for an equivalent of something called Nic-A-Date, which is an acid that can bring out the date on a worn buffalo nickel. Unfortunately there isn't any commercial product like that for copper coins. Nic-A-Date works because most dateless buffalo nickels are the result of a design defect that left the date higher than the rest of the coin when new, so it wore off first. When a coin is struck the impression slightly deforms and compresses the metal below its surface, and Nic-A-Date etches away some of the uncompressed metal revealing the "ghost" image of the date below the surface. The problem with any acid treatment is that it damages the coin's surface. Even if you were to reveal a valuable date, the coin's collector value would be significantly reduced or even eliminated.
What are the word equations for sulphric acid and copper nitrate?
Sulfuric acid plus copper (II) nitrate yields nitric acid plus copper (II) sulfate. Sulfuric acid plus copper (I) nitrate yields nitrous acid plus copper (I) sulfate.
Would copper melt in acid?
Only if the acid is above the melting point of copper. However, the copper might dissolve in acid if the acid is oxidizing. If it did, copper ions would be present in the solution formed, but there would not be an metallic copper in it.
Does copper dissolve in acid?
Yes, copper can dissolve in acid, specifically nitric acid, sulfuric acid, or hydrochloric acid. When exposed to these acids, copper ions are formed through a redox reaction, resulting in the dissolution of copper.
Is copper sulfate an acid or a base?
Copper sulfate is an acid.
How do you re-tone acid dipped copper coins?
The process may be natural during time.

Copper sulfate is an acid.
What does copper and nitric acid equal?
Copper reacts with nitric acid to form copper nitrate, nitrogen dioxide gas, and water. The reaction is a redox reaction where copper is oxidized and nitric acid is reduced. Be cautious when handling nitric acid as it is a strong acid and can be corrosive.
Is copper an acid?
No, copper is not an acid. Copper is a chemical element (Cu) that is a metal and is not classified as acidic.
What acid reacts with copper to make copper sulphate?
Sulfuric acid reacts with copper to produce copper sulfate. Copper sulfate is formed when copper reacts with sulfuric acid in the presence of oxygen.
What happens when copper is placed in acid?
When copper is placed in acid, a chemical reaction occurs where the copper reacts with the acid to form copper ions and hydrogen gas. This reaction results in the copper dissolving in the acid and producing a blue-green solution.
What happen when sulphuric acid is poured on copper plate?
equation = copper+suphuric acid=copper sulphate+hydrozen
Why do acids clean copper coins the best?
Acids are effective at cleaning copper coins because they can dissolve the oxide layer that forms on the surface of the coins, revealing the clean copper metal underneath. The acid reacts with the oxide layer, breaking it down and making it easier to remove. However, acids must be used carefully as they can also corrode the copper if left on for too long.
