(i) Al2(SO4)3

Aluminium sulphate

(ii) CaCl2

Calcium chloride

(iii) K2SO4

Potassium sulphate

(iv) KNO3

Potassium nitrate

(v) CaCO3

Calcium carbonate

Explanation:

Thisis the correct answer of your question.

Answer 2

(i) Al2(SO4)3 - Aluminium Sulphate.

Ions present are : Al³+and (SO4)²-

(ii) CaCl2 - Calcium Chloride.

Ions present are: Ca²+ and Cl-

(ii) K2SO4 - Potassium Sulphate.

Ions present are : K+ and SO2²-

(iv) KNO3 - Potassium Nitrate.

Ions present are : K+ and NO³-

(v) CaCO3 - Calcium Carbonate.

Ions present are: Ca²+ and CO3²+
