Vedclass · Accepted Answer

It does not give the test of $Fe^{2+}$ ion.

Vedclass · Answer

(C) Mohr's salt is represented by the formula $(NH_4)_2SO_4 \cdot FeSO_4 \cdot 6H_2O$.It is a double salt that dissociates completely in water into its constituent ions: $2NH_4^+$,$Fe^{2+}$,and $2SO_4^{2-}$.$1$. It has $2 + 1 + 2 = 5$ ions per formula unit,so option $A$ is correct.$2$. It is a double salt,so option $B$ is correct.$3$. Since it dissociates into $Fe^{2+}$ ions in aqueous solution,it gives a positive test for $Fe^{2+}$,making option $C$ incorrect.$4$. It contains two types of cations,$NH_4^+$ and $Fe^{2+}$,so option $D$ is correct.Therefore,the wrong statement is $C$.

Which among the following statements is wrong regarding Mohr's salt?
