Oxides, Hydroxides and Ammonia.

Metal Oxides and Metal Hydroxides Are Bases.

1) Some metal oxides and metal hydroxides dissolve in water. These soluble compounds are alkalis.

2) Even bases that won't dissolve in water will still react with acids.

3) So, all metal oxides and metal hydroxides react with acids to form a salt and water.

                     ACID + METAL OXIDE -----------> SALT + WATER

              ACID + METAL HYDROXIDE ------------> SALT + WATER

                       (These are neutralisation reactions of…
