Activity 2.13 Class 10 Science

This activity helps students understand how salts are formed from acids and bases through neutralization reaction.

Table of Contents

To write chemical formulae of salts, to identify the parent acid and bases and to classify salts into families.

Table

1. Sodium salts

These salts contain Na⁺ ions – Na₂SO₄, NaCl , NaNO₃, Na₂CO₃

2. Sulphate salts

These salts contains SO₄^2- ions – K₂SO₄,Na₂SO₄,CaSO₄,MgSO₄, CuSO₄

3. Chloride salts

These salts contain Cl^– ions – NaCI , NH₄CI

4. Nitrate salts

These salts contain NO₃^– ions – NaNO₃

5. Carbonate salts

These salts contain CO₃^2- ions – Na₂CO₃

6. Ammonium salts

These salts contain NH₄⁺ ions – NH₄Cl

We can conclude –

1. Six families based on positive and negative ions.

2. This classification helps us understand the composition and nature of salts.
