Storage
Store in a cool, dry place in tightly closed containers. Stable under
normal temperatures and pressures. When kept for a long time at
60-65°C (or over sulfuric acid) potassium alum dodecahydrate
loses water, which is reabsorbed on exposure to air. It becomes
anhydrous at about 200°C.Store at RT.
