Alum – Formula, Types, Production, Properties, Uses
Alum is an important inorganic compound which are double sulfates of a monovalent metal (such as potassium, sodium, or ammonium) and a trivalent metal (such as aluminum, chromium, or iron). Alum is widely used in industries as well as medical purposes. It has antiseptic property and is used after shave. It is often called “Fitkari.”
