Potassium alum dodecahydrate occurs in nature as a sulfate mineral called alum-(K), typically as encrustations on rocks in areas of weathering and oxidation of sulfide minerals and potassium-bearing minerals. In the past, potassium alum has been obtained from alunite (KAl(SO 4) 2·2Al(OH) 3), mined from sulfur-containing volcanic sediments. Alunite is an associate and likely potassium and aluminiu… WebbThe given salt is formed by joining the sulfate ion with the aluminum and potassium metal so it is an inorganic salt.
