Chemical hydroxides are very basic salts. As metal salts, they are usually very insoluble, but alkali hydroxides are very soluble, inexpensive bases.

Properties

Chemical

Hydroxides are usually basic, and can be neutralized by acids (releasing the salt and water).

Physical

Alkali hydroxides are very soluble and very basic, while other hydroxides are usually only slightly basic and insoluble.

Production

Addition of an alkaline metal oxide to water gives hydroxide.
