Alkali salts or base salts are salts that are the product of incomplete neutralization of a strong base and a weak acid.

Rather than being neutral (as some other salts), alkali salts are bases as their name suggests. What makes these compounds basic is that the conjugate base from the weak acid hydrolyzes to form a basic solution. In , for example, the from the to form a basic solution. The chloride from the hydrochloric acid in does not hydrolyze, though, so sodium chloride is not basic.

The difference between a basic salt and an alkali is that an alkali is the soluble hydroxide compound of an alkali metal or an alkaline earth metal. A basic salt is any salt that hydrolyzes to form a basic solution.

Another definition of a basic salt would be a salt that contains amounts of both hydroxide and other anions. is an example. It is basic lead carbonate, or lead carbonate hydroxide.

These materials are known for their high levels of dissolution in polar solvents.

These salts are insoluble and are obtained through precipitation reactions.
