What is dehydrated salt?

Dehydrated salt, often referred to as anhydrous salt, is a form of salt that has had its water content removed, resulting in a dry, crystalline substance. This process enhances the salt's shelf life and makes it more effective in certain applications, such as in chemical processes or as a desiccant. Common examples include anhydrous sodium sulfate and magnesium sulfate. Dehydrated salt is typically used in industrial applications, food preservation, and in laboratories.
