Sodium hydroxide is obtained from salt, yes. The manufacture of this strong base is accomplished mainly from what is termed the chloralkali process. This is the electrolysis of a salt solution which produces sodium hydroxide and also chlorine and hydrogen gas. It is an industrial process that is important to the chemical industry.

What is a hydroscopic salt?

A hygroscopic salt is a salt that readily absorbs water from the atmosphere, either to form a solution (hygroscopicity) or to become damp (deliquescence). This property makes hygroscopic salts useful for controlling humidity in certain applications, such as in food processing or as drying agents in laboratories.
