Acids, Bases and Salts | Class 10 | Activity 2.13 with Solution

Activity 2.13  

• Write the chemical formulae of the salts given below.

Potassium sulphate, sodium sulphate, calcium sulphate, magnesium sulphate, copper sulphate, sodium chloride, sodium nitrate, sodium carbonate and ammonium chloride.

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

✅ Answer:

Salts & their Chemical formulae	Formed from which Acids & bases?
Potassium sulphate (K2SO4)	H2SO4 & KOH
Sodium sulphate (Na2SO4)	H2SO4 & NaOH
Calcium sulphate (CaSO4)	H2SO4 & CaCO3
Magnesium sulphate (MgSO4)	H2SO4 & Mg(OH)2
Copper sulphate (CuSO4)	H2SO4 & Cu(OH)2
Sodium chloride (NaCl)	HCl & NaOH
Sodium nitrate (NaNO3)	HNO3 & NaOH
Sodium carbonate (Na2CO3)	H2CO3 & NaOH
Ammonium chloride (NH4Cl)	HCl + NH4OH

• Salts having the same positive or negative radicals are said to belong to a family. For example, NaCl and Na2SO4 belong to the family of sodium salts. Similarly, NaCl and KCl belong to the family of chloride salts. How many families can you identify among the salts given in this Activity?

✅ Answer: Na₂SO₄, NaCl, NaNO₃ and Na₂CO₃ belong to the family of sodium salts. K₂SO₄, Na₂SO₄, CaSO₄, MgSO₄, CuSO₄ belong to the family of sulphate salts. NaCl and KCl belong to the family of chloride salts.
