Some metals react with acids and when they do the products are hydrogen gas and a solution of the salt. A salt is a type of compound which is made when an acid reacts with certain metals.

Instead of immersing entire sheets of metal into acidic solutions, the researchers applied microdroplets of acidic solution onto small aluminum surfaces and applied an electric current.

MOST text-books of organic chemistry contain the statement that formic acid and formates owe ... ammoniacal silver nitrate to the metal; while this reaction certainly is given by aldehydes ...

If there's a reaction, we'll pull it out ... That way, there's no further rusting from the acid because the acid does attack the metal slightly. Then it'll be pressure washed until all of the ...
