Answer & Solution
Correct Answer
(A) common ion effect
Step-by-step Solution
Detailed explanation
\(\mathrm{NaCl}\) on dissociation gives \(\mathrm{Na}^{+}\)and \(\mathrm{Cl}^{-}\)ions as follows: \[ \underset{\text { Sodlum chloride }}{\mathrm{NaCl}(a q)} \longrightarrow \underset{\text { Common ions }}{\mathrm{Na}^{+}}+\mathrm{Cl}^{-} \text {(ions) } \] While, soap in the…
