Explanation:
Ion Product and Solubility Product:
- The solubility product (Ksp) is the product of the concentrations of the ions in a saturated solution of a salt at a particular temperature.
- The ionic product is the product of the concentrations of the ions in a solution at any given time.
Precipitation of NaCl:
- When HCl gas is passed through a saturated solution of common salt (NaCl), it reacts with the Na+ ions to form NaCl and H+ ions.
- This reaction causes the concentration of Cl- ions to increase in the solution.
- As a result, the ionic product [Na+] [Cl-] exceeds the solubility product (Ksp) of NaCl.
- When the ionic product exceeds the solubility product, the excess ions combine to form a solid precipitate of NaCl.
Reasoning:
- Option B is the correct answer because the precipitation of pure NaCl occurs due to the exceeding of the ionic product [Na+] [Cl-] over the solubility product (Ksp) of NaCl.
- The presence of Cl- ions in the solution due to the reaction with HCl gas leads to the formation of a precipitate of NaCl.
- This process is driven by the principles of chemical equilibrium and solubility product constants.
In conclusion, passing HCl gas through a saturated solution of NaCl results in the precipitation of pure NaCl due to the exceeding of the ionic product over the solubility product of NaCl.
