Question

The mixed salt among the following is:-

• A. $KOOCC{H}_2-C{H}_{2}COONa$
• B. $NaK{SO}_4$
• C. $CaO{Cl}_2$
• D. All the above

Answer 1

The correct option is D All the above

A mixed salt furnishes two types of cations or anions.
$NaK{SO}_4\to N{a}^{+}+K^{+}+S{O}_4^{-2}$

$CaO{Cl}_2\to C{a}^{+2}+OC{l}^{-}+C{l}^{-}$

$KOOCC{H}_2-C{H}_{2}COONa\to K^{+}+N{a}^{+}{+}^{-}OOCC{H}_{2}C{H}_{2}CO{O}^{-}$

So, all are correct
