The result of adding a small crystal of NaCl to a saturated solution of NaCl is that:
the same crystal precipitates
a larger amount of NaCl precipitates
the crystal dissolves in solution
the same amount of NaCl precipitates
On passing a current of HCl gas in a saturated solution of NaCl, the solubility of NaCl ________
When in a saturated solution of NaCl, HCl is passed, pure precipitate of NaCl is formed. This is due to the fact:
