A substance that reacts with an acid to form a salt and water.
A substance that reacts with an acid to form a salt and water. Bases are usually metal oxides, metal hydroxides, or metal carbonates. Bases accept a hydrogen ion in reactions, and produce hydroxide ions in solutions. Most bases are insoluble in water, but if a base dissolves in water the solution is termed an alkali, and will always have a pH greater than 7.
