Alkali metal hydroxides such as sodium hydroxide are strong bases and are very soluble in water; alkaline–earth metal hydroxides such as calcium hydroxide (slaked lime) are much less soluble in water and are not as strongly basic.
Some hydroxides (e.g., aluminumhydroxide) exhibit amphoterism, having either acidic or basic properties depending on the reaction in which they are involved.
Ammonium hydroxide, NH OH, is a weak base known only in the solution that is formed when the gas ammonia, NH, dissolves in water.
