ACIDS AND BASES
Acids have a pH of less than 7.
Bases have a pH of more than 7.
When Bases are dissolved in water, they are known as alkalis.
Salts are made when an Acid reacts with a Base, Carbonate or Metal.
The name of the salt formed would depend upon the metal in the base and the acid used. (example - salts made from hydrochloric acid, make chlorides)
The more strongly acidic the solution, the lower the pH number.
