JEE Main 7 April 2025, Shift 1, Chemistry Q55

Question 55 of 75 in this shift, Chemistry question 5 of 25, Section A.

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 x1x_1, x2x_2 and x3x_3 S cm2 mol−1\mathrm{cm^2\,mol^{-1}}, respectively then the molar conductance for Mohr's salt solution at infinite dilution would be given by x1+x2+2x3x_1 + x_2 + 2x_3 In the light of the given statements, choose the correct answer from the options given below:
  1. (1)Both Statements I and Statement II are true
  2. (2)Both Statements I and Statement II are false
  3. (3)Statement I is true but Statement II are falseOfficial answer
