Acids react with metal oxides and hydroxides to produce a salt and water.

acid + metal oxide → salt + water

acid + metal hydroxide → salt + water

For example:

hydrochloric acid + copper(II) oxide → copper(II) chloride + water

2HCl + CuO → CuCl2+ H2O

nitric acid + calcium hydroxide → calcium nitrate + water

2HNO3+ Ca(OH)2→ Ca(NO3)2+ 2H2O
