When metals react with acids, a salt of the metal and hydrogen gas are formed. We can investigate the reactivity of different metals by placing samples in acid and comparing the results.

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 ...

Do not attempt to perform this demonstration. Small pieces of solid calcium metal are placed in two different concentrations of two different acids (hydrochloric acid and nitric acid). The calcium ...
