When an acid is added to an alkali the pH of the acid increases towards 7 and the pH of the alkali decreases towards 7.

This is measured using the pH scale, which runs from pH 0 to pH 14. Neutral solutions have a pH of 7 Acids have a pH less than 7 Alkalis have a pH greater than 7 Universal indicator has many ...
