Strong bases are bases which completely dissociate in water into the cation and OH- (hydroxide ion). The hydroxides of the Group I and Group II metals usually are considered to be strong bases. Some common/strong bases:
- LiOH: Lithium hydroxide is mainly consumed for the production of lithium greases. A popular lithium grease is lithium stearate, which is a general-purpose lubricating grease due to its high resistance to water and usefulness at both high and low temperatures.
- NaOH: Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as adrain cleaner. Worldwide production in 2004 was approximately 60 million tonnes, while demand was 51 million tonnes.
- Ba(OH)2: Also known as baryta, it is one of the principal compounds of barium. Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularlyorganic acids.
