Will Hydrochloric Acid 38% be strong enough to melt through metal?

If not, how strong would it need to be?


Metals like steel, aluminum, iron, and alloys of those metals.

    There needs to be a few things set straight.....

    First of all, acids don't melt metal. They oxidize the solid metal, forming soluble salts. When the salts rince away, it carries the oxidized metal with it.

    Next, Hydrochloric acid is just a solution of a very water soluble gas. However, Hydrogen chloride gas can't mix with water in concentrations any greater than 22% by weight. This is what concentrated Hydrochloric acid is.

    As noted, not all metals will react with Hydrochloric acid. Metals like Gold, Platinum, Iridium and Rhodium are very inert. Most ordinary metals like Iron, Copper, Tin and Aluminum will react. The products are metal salts and Hydrogen gas.

    FYI: A mixture of Hydrochloric and Nitric acids is known as "aqua regia". It is powerful enough to dissolve many inert metals, including Gold. Hydroffluoric acid is strong enough to dissolve glass. However, most plastic is unaffected by it. Fluorine gas itself is the most reactive substance in chemistry. Metal will actually burn like paper if exposed to this gas.

    What metal?

    Gold is a metal and hydrochloric acid won't touch it.
