Properties of alkaali.

• Alkali are metallic hydroxides of alkaline metals, which in solution ionize to hydroxyl ions that can bind H to form H2O and thereby can remove hydrogen ion from solution.
• Strong alkalis are those which rapidly and almost completely ionize to hydroxyl ions that quickly remove hydrogen ion from solution.
• Weak alkalis are those which slowly and partially ionize to hydroxyl ions that slowly remove hydrogen ion from solution.
• In fact all alkalis are also regarded as base, but all bases are not alkalis.
