13. Complete Activity 2.13 (Page 28).
- 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.
- 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:
The chemical formulae of the given salts, the acids and bases from which these salts have been obtained and the family the salts belong to are given in the table below:
| Salt | Chemical Formulae | Acid and base from which salt was obtained | Family |
| Potassium sulphate | K2SO4 | Acid – H2SO4, Base – KOH | Potassium salts |
| Sodium sulphate | Na2SO4 | Acid – H2SO4, Base – NaOH | Sodium salts |
| Calcium sulphate | CaSO4 | Acid – H2SO4, Base – Ca(OH)2 | Calcium salts |
| Magnesium sulphate | MgSO4 | Acid – H2SO4, Base – Mg(OH)2 | Magnesium salts |
| Copper sulphate | CuSO4 | Acid – H2SO4, Base – Cu(OH)2 | Copper salts |
| Sodium chloride | NaCl | Acid – HCl, Base – NaOH | Chloride salts |
| Sodium nitrate | NaNO3 | Acid – HNO3, Base – NaOH | Nitrate salts |
| Sodium carbonate | Na2CO3 | Acid – H2CO3, Base – NaOH | Carbonate salts |
| Ammonium chloride | NH4Cl | Acid – HCl, Base – NH4OH | Chloride salts |
