An alkali, which almost dissociates completely in an aqueous solution, thereby producing high concentration of OH^- ions is called a strong alkali. For example, lithium hydroxide, sodium hydroxide and potassium hydroxide. An alkali, which dissociates partially in an aqueous solution, thereby producing a low concentration of OH^- ions is called a weak alkali. For example, ammonium hydroxide, calcium hydroxide and magnesium hydroxide.
