Answer 2

The correct option is d KCl.

The correct option is d KCl. KCl is not a mixed salt.

• Those salt which have more than one cation or anion is called mixed salt.
• The dissociation of the above salts are-
• $KCaPO_4\rightarrow K^++Ca^{+2}+PO_4^-$
• $Ca(OCl) Cl\rightarrow Ca^{+2}+O^{2-}+2Cl^-$
• $NaKCO_3\rightarrow K^++Na^{+}+CO_3^{2-}$
• $KCl\rightarrow K^++Cl^{-}$

Only KCl give a single cation and anion so, it is not a mixed salt.
