Both MgCl 2 _2 2 and CaCl 2 _2 2
and NaCl
the solubility of these salts is affected by the common ion effect.
•
NaCl:
The solubility of NaCl is relatively low compared to the other chlorides.
When HCl is added, the concentration of Cl
ions increases, which decreases the solubility of NaCl due to the common ion effect.
Thus, NaCl is likely to crystallize out of the solution.
•
MgCl
MgCl
is more soluble in water than NaCl. However, the addition of HCl increases the Cl
ion concentration, which can also lead to a decrease in the solubility of MgCl
However, it is less likely to crystallize compared to NaCl.
•
CaCl
CaCl
is highly soluble in water, and the addition of HCl does not significantly affect its solubility.
Therefore, it is unlikely to crystallize out of the solution.
Based on the above analysis, the most likely compound to crystallize is NaCl.
Therefore, the correct answer is Option 1: Only NaCl.
