Given below are two statements :
Statement I : Mohr's salt is composed of only three types of ions-ferrous, ammonium and sulphate.
Statement II : If the molar conductance at infinite dilution of ferrous, ammonium and sulphate ions are ${\mathrm{x}}_{1},{\mathrm{x}}_{2}$ and ${\mathrm{x}}_{3}\mathrm{S}{\mathrm{cm}}^{2}{\mathrm{mol}}^{-1}$, respectively then the molar conductance for Mohr's salt solution at infinite dilution would be given by ${\mathrm{x}}_{1}+{\mathrm{x}}_{2}+2{\mathrm{x}}_{3}$
In the light of the given statements, choose the correct answer from the options given below

YESPYQ · Accepted Answer

Correct answer: c) Statement I is true but Statement II are false. Mohr's salt : FeSO 4 (NH 4 ) 2 SO 4 .6H 2 O Using Kohlrousch law ${\lambda }_{\mathrm{m}}^{\infty }$(Mohr's salt) = x 1 + 2x 2 + 2x 3
