Question

on heating a given mass of blue vitriol 95.7 grape anhydrous copper sulphate is obtained the number of water molecules lost​

Answer 1

Answer:

5 molecules of water are lost during the heating of blue vitriol.

Explanation:

Hydrous copper sulphate is called blue vitriol. Copper sulphate has tendency to change its color upon contact with water. Usually anhydrous copper sulphate remains white until it gets in contact with moisture or water to become blue. Hydrated copper sulphate becomes blue which contains 5 molecules of water tightly embedded in between metallic atoms. Water gets evaporated upon heating and anhydrous copper sulphate is left which is white in color.
