Why plaster of Paris should be stored in a moisture-proof container??? |
|
Answer» Bcoz in presence of moisture it turned to gypsum which is a hard mass and can no be longer used for making statues etc. Because presence of moisture can cause slow setting of plaster of paris by bringing its hydration which make it useless after some time Cause if it come in contact eith water it will be converted into gypsum... CuSO4.2h2O |
