Which of the following expressions correctly represents the equivalent conductance at infinite dilution of Al ₂ ( SO ₄ )₃ . Given that _ Al ³⁺ ^ and _ SO ₄²⁻ ^ are the equivalent conductances at infinite dilution of the respective ions?

Options

  1. A2 _ Al ³⁺ ^ +3 _ SO ₄²⁻ ^
  2. B_ Al ³⁺ ^ + _ SO ₄²⁻ ^
  3. C( _ Al ^ + ^ +3 _ SO ₄²⁻ ^ ) 6
  4. D1 3 _ Al ³⁺ ^ + 1 2 _ SO ₄²⁻ ^

Correct answer

B. _ Al ³⁺ ^ + _ SO ₄²⁻ ^

Step-by-step solution

Al ₂ ( SO ₄ )₃ 2 Al ³⁺+3 SO ₄²⁻ Since equivalent conductances are given only for ions, the equivalent conductance at infinite dilution, _ eq ^ = _ Al ³⁺ ^ + _ SO ₄²⁻ ^
