If water is added to the cold white powder the water recombines with the calcium(II) sulfate to form hydrated calcium(II) sulfate or plaster of Paris. As this happens the mixture gets hot which chemists call an exothermic chemical reaction.

What happens when plaster of Paris react with water?

When Plaster of Paris is mixed with water, a crystallization reaction occurs which leads to the formation of orthorhombic calcium sulphate dihydrate. … The powder changes to a paste and finally turns into a solid compound which is monoclinic calcium sulphate dihydrate or basically gypsum.

What is formed when Plaster of Paris is mixed with water?

actually, plaster of Paris is formed by heating of gypsum at 140°C to 180°C. so, if we mix plaster of Paris of Paris with water, it becomes hard to form gypsum. e.g., hence, plaster of Paris on mixing with water produces gypsum.
