Question

A.write the chemical names and formula of three hydrated salts

Answer 1

it's. a.copper sulphate CuSo4.5H2O. b. ferrous sulphate FeSo4.7H2O. c. sodium carbonate decahydrate Na2Co3.10H2O.

Answer 2

The chemical names and formulas of the three hydrated salts are explained below:

• The three hydrated salts are FeSo4 7H2O, CuSO4.5H2O and Na2CO3.10H2O.
• Na2SO4.10H2O is known as Glauber's salt and is a laxative.
• It is used to neutralise the effect of overdoses of paracetamol and is a diuretic.
• FeSo4. 7H2O is green coloured and decomposes to FeSo4 on heating and becomes white.
• CuSO4.5H2O is blue coloured and on heating becomes white.
• CuSO4.5H2O has coordinate, hydrogen bonding, ionic and covalent bonding.
