Gypsum is a hydrated calcium sulfate mineral with the chemical formula CaSO4·2H2O. The mineral is made of calcium (Ca), sulfur (S), oxygen (O), and water (H2O). Discover the chemical formula for Gypsum, Calcium Sulfate Dihydrate (CaSO4.2H2O). Learn its composition and distinguish it from Plaster of Paris and Anhydrite. The correct answer is CaSO4.1/2 H2O. EXPLANATION: Plaster of Paris (POP) is a quick-setting gypsum plaster consisting of a fine white powder (calcium sulfate hemihydrate), which hardens when moistened and allowed to dry. It is also known as the Plaster of Paris because for the preparation of POP, the abundant gypsum was first found near the capital city of France i.e. Paris. The chemical formula of the Plaster of Paris is CaSO4. 1 2 H2O. Therefore option 3 is correct. Application of Plaster ... Gypsum is a naturally occurring mineral that has been used by humans for various purposes for thousands of years. It is a versatile mineral with a wide range of applications in construction, agriculture, industry, and even art. In this introduction, we'll explore the definition and composition of gypsum.
