What type of acid do you need to melt metal?

Answer 1

Acids don't actually melt metal, they oxidize or corrode them. Usually producing the corresponding metal salt and hydrogen gas.

Most strong acids (hydrochloric, hydrobromic, hydroiodic, perchloric, nitric, and sulfuric acids) will oxidize metals in this manner. Some weak acids such as hydrofluoric acid can oxidize metals. Some metals, such as the alkali metals and alkaline earth metals will react with virtually any acid and even water.

Nitric acid can oxidize copper, which normally doesn't react with acid.

Aqua regia, a mixture of nitric acid and hydrochloric acid will oxidize gold and platinum, which are usually considered immune to corrosion.

Answer 2

To melt metal, you would typically use a strong acid like hydrochloric acid or nitric acid. These acids are capable of breaking down the metal's molecular structure, allowing it to melt at high temperatures. However, it's important to note that working with these acids can be extremely dangerous and should only be done by trained professionals in a controlled environment.

Answer 3

Acid doesn't melt metal it oxidizes (corrodes) it.

What acid you need depends on the metal. Though a strong acid such as sulfuric acid or hydrochloric acid will usually work.
