B
HCl is slightly soluble in water
C
the ionic product 
exceeds the solubility product of NaCl
exceeds the solubility product of NaCl D
the solubility product of NaCl is lowered by 
from 
.
from .
Text Solution
Verified by ExpertsThe correct answer is:
C
The added HCl increases 
concentration, so the ionic product 
exceeds 
of NaCl , causing NaCl to precipitate (common ion effect).
