What Happens When Metals React With Acids? | …

While exploring what happens when metals come in contact with acids, it is apparent that most, but not all, have some sort of reaction, usually forming hydrogen gas. The result is the production of salts. Hydrochloric Acid Some metals dissolve in this acid and this results in the formation of hydrogen gas and oxidized metal chlorides.
