Question

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 ,  and  S cm mol, respectively then the molar conductance for Mohr's salt solution at infinite dilution would be given by .

In the light of the given statements, choose the correct answer from the options given below:

Canvas Classes · Accepted Answer

Strategy:
 Identify the components of Mohr's salt and apply Kohlrausch's Law of independent migration of ions. Sum the molar ionic conductivities multiplied by their stoichiometric coefficients.

Step 1: Identify Mohr's Salt
Formula: 
Ions produced in solution:

Types of ions: Ferrous (), Ammonium (), and Sulphate ().
Statement I is Correct. ✓

Step 2: Apply Kohlrausch's Law

Using given variables:

Statement II claims , which is Incorrect (missing the factor of 2 for Ammonium).
