Also known as a base, an alkali is chemically defined as a donor of hydroxyl ions (each of which comprises an atom of hydrogen linked to an atom of oxygen and has an overall negative electrical charge). Antacid drugs, such as sodium bicarbonate, are alkalis. Some alkalis, such as sodium hydroxide, are corrosive. (See also acid; acid–base balance.)
A substance which neutralises an acid to form a salt, and turns litmus and other vegetable dyes blue. Alkalis are generally oxides or carbonates of metals.
In our context, a substance having a pH above that of neutral water (7.0) when in solution. Signified as pH (potential of Hydrogen), alkaline fluids, such as the blood (pH about 7.4), have the ability to neutralize acids (solutions below pH 7.0). Metabolic wastes are acids, and the alkaline reserve of the blood neutralizes them until they are excreted. See pH... alkaline

A rare type of hypercalcaemia accompanied by alkalosis and kidney failure. The syndrome is due to excessive, long-term intake of calciumcontaining antacid drugs and milk. It is most common in people with a peptic ulcer and associated kidney disorders. Symptoms include weakness, muscle pains, irritability, and apathy. Treatment is to reduce milk and antacid intake.... milk–alkali syndrome
