Question

Given below are two statements : Statement I : Mohr's salt is composed of only three types of ions-ferrous, ammonium and sulfate. Statement II : If the molar conductance at infinite dilution for ferrous, ammonium and sulfate ions are x1, x2 and x3 S cm2 mol–1, respectively then the molar conductance for Mohr's salt solution at infinite dilution would be given by x1 + x2 + 2x3 In the light of the given statements, choose the correct answer from the options give below : (A) Statement I is true but Statement II are false (B) Both Statement I and Statement II are false (C) Statement I is false but Statement II is true (D) Both Statement I and Statement II are true

Answer: A

💡 Solution & Explanation

Mohr's salt : FeSO4.(NH4)2SO4.6H2O using kohlrousch law  m (Mohr's salt) = x1 + 2x2 + 3x3
