Question

Write the formulae of the salts given below:

Potassium sulphate, sodium sulphate, calcium sulphate, sodium nitrate, magnesium carbonate, ammonium chloride, sodium chloride, calcium carbonate, sodium acetate, ammonium chloride.

2 Identify the acids and bases from which the above salts may be obtained.

3 Identify the families of the above salts.

Answer 1

Potassium sulphate is salt of caustic potash i.e. Potassium hydroxide (KOH)" and "sulphuric acid(H2SO4)"  

Sodium Sulphate is salt of caustic soda i.e.“Sodium hydroxide (NaOH)” and “sulphuric acid (H2SO4)”  

Calcium sulphate is salt of “Calcium Hydroxide (Ca(OH)2)” and “sulphuric acid (H2SO4)”  

Magnesium Sulphate is salt of Magnesium "hydroxide (Mg(OH)2)” and “sulphuric acid (H2SO4)”.  

Copper sulphate is salt of “Cupric hydroxide (Cu(OH)2)” and “sulphuric acid”  

Sodium chloride is salt of “Sodium hydroxide and hydrochloric acid

Sodium nitrate is salt of “Sodium Hydroxide and nitric acid (HNO3)”  

Sodium Carbonate is salt of “Sodium hydroxide and carbonic acid (H2CO3)”

Ammonium chloride is salt of “Ammonium hydroxide (NH4OH)” and hydrochloric acid
