MCQ
Mohr's salt is
  • A
    $FeS{O_4}.7{H_2}O$
  • B
    $Fe(N{H_4})S{O_4}.6{H_2}O$
  • ${(N{H_4})_2}S{O_4}.FeS{O_4}.6{H_2}O$
  • D
    $[Fe{(N{H_4})_2}]\,{(S{O_4})_2}.6{H_2}O$

Answer

Correct option: C.
${(N{H_4})_2}S{O_4}.FeS{O_4}.6{H_2}O$
c
Mohr's salt or Ferrous ammonium sulphate is the inorganic compound with the formula $\left( NH _4\right)_2 F$ e $\left( SO _4\right)_2 \cdot 6 H _2 O$. It contains two different cations $Fe ^{2+}$ and $NH _4^{+}$hence, also classified as a double salt.
