Hydration Of Anhydrite: Gypsum could also sort in the hydration of anhydrite (CaSO₄). Anhydrite is a calcium sulfate mineral that lacks the drinking water molecules existing in gypsum. When subjected to h2o, anhydrite undergoes a hydration response, incorporating h2o molecules into its framework and reworking into gypsum.
