The chemical equation for this reaction is: CaSO₄ . 1/2 H₂O + 3/2H₂O →CaSO₄ . 2H₂O This equation represents the addition of water molecules to Plaster of Paris, resulting in the formation of Gypsum, which is a hydrated calcium sulfate compound. The reaction is exothermic, and during the process, the plaster solidifies as it returns to its original state of Gypsum. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Click on image to update the captcha.
