Question
What happens to the solubility of a saturated solution of NaCl, when a current of HCl gas is passed through it?
Answer: Option B
:
B
When HCl gas is passed through a saturatedNaClsolution, the number of Cl−1 ions increases. The increased number ofCl−1 interact with Na+1 ions to form crystallised NaCl. Thus, the solubility of NaCl decreases and it is recovered in crystalline form. This phenomenon is called "common ion effect".
