Following limiting molar conductivities are given as given as aligned & _ m ( H ₂ SO ₄ ) ^0= x S cm ^2 ~mol ⁻¹ & _ m ( K ₂ SO ₄ ) ^0= y S cm ^2 ~mol ⁻¹ & aligned _ m ( CH ₂ COOK ) ^0= Z S cm ^2 ~mol ⁻¹

Options

  1. Ax-y+2 z
  2. Bx+y-z
  3. Cx-y+z
  4. D(x-y) 2 +z

Correct answer

D. (x-y) 2 +z

Step-by-step solution

Key Idea According to Kohlrausch's law, _m^0 for A_x B_y=x _ (A)⁰⁺ ^0+y _ (B)^ x- where, _m^ = limiting molar conductivity of electrolyte and _ (A)^ y+ ^0 and _ (B)^ x- ^0 are the limiting molar conductivities of cation (A^ y+ ) and anion (B^ x- ) , respectively.
