Molar conductance of an electrolyte increases with dilution according to the equation: _ m = _ m ^ - A c Which of the following statements are true? (A) This equation applies to both strong and weak electrolytes. (B) Value of the constant A depends upon the nature of the solvent. (C) Value of constant A is same for both BaCl ₂ and MgSO ₄ . (D) Value of constant A is same for both BaCl ₂ and Mg ( OH )₂ . Choose the mo

Options

  1. A(B) and (C) only
  2. B(B) and (D) only
  3. C(A) and (B) only
  4. D(A),(B) and (C) only

Correct answer

B. (B) and (D) only

Step-by-step solution

_m= _m^ -A c - For strong electrolytes, _ m increases slowly with dilution. - The value of ' A ' depends on the type of electrolyte. - All electrolytes of particular type have the same value for 'A' e.g. BaCl ₂ and Mg ( OH )₂ 2-1 electrolytes
