Answer 2

A salt which shows a sharp break in its solubility at 36°C and becomes anhydrous is Na2SO4. 10H2O.

• Decahydrate Sodium sulphate is also known as Glauber's salt.
• It is very unstable in dry air and undergoes dehydration which results in the formation of a white powder which is Na2SO4.
• However the melting point of Glauber's salt is 32.38°C.
• Glauber's salt got it's name from a Dutch/German chemist Johann Rudolf Glauber.
