(d) ZnCO3
(e) Mg(OH)2

Answer 1

Answer:

a) Mg⁺² (Magnesium)  is Basic Radical  &  SO₄⁻²(Sulphate) is Acidic Radical

b) NH₄⁺¹(Ammonium) is Basic Radical &  SO₄⁻²(Sulphate) is Acidic Radical

c) Al⁺³ (Aluminium) is Amphotheric (here, it could be considered Basic)  &   SO₄⁻²(Sulphate) is Acidic Radical

d)Zn⁺² (Zinc) is Amphotheric (here, it could be considered Basic) & CO₃⁻²(Carbonate) is Acidic Radical

e) Mg⁺² (Magnesium)  is Basic Radical  & OH⁻¹ (Hydroxide) is Acidic Radical

Explanation:

All the Anions are Acidic Radical, they are mostly Non-Metals

Almost all the cations are Basic (Some are Amphotheric), they are all metals
