Question

write an activity to show how crystal are formed with the help of water ​. please answer fast it's very very very urgent ​

Answer 1

Explanation:

Water of crystallisation is the number of water molecules that are bound to the crystalline form of the salt in stoichiometric proportion.

Examples:

CuSO4.5H2O copper(II) sulphate pentahydrate. Water of crystallisation is 5

CaCl2.6H2O calcium(II) chloride hexahydrate. Water of crystallisation is 6

BaCl2.2H2O barium(II) chloride dihydrate. Water of crystallisation is 2.

When crystalline copper sulphate is heated it loses all the five water molecules. The blue crystalline hydrate is converted to white amorphous solid.

CuSO4.5H2O →Δ CuSO4 + 5H2O
