Consider the statements S 1 and S 2 : S 1 : Conductivity always increases with decreases in the concentration of electrolyte. S 2 : Molar conductivity always increases with decreases in the concentration of electrolyte. The correct option among the following

Options

  1. AS 1 is wrong and S 2 is correct
  2. BS 1 is correct and S 2 is wrong
  3. CBoth S 1 and S 2 are correct
  4. DBoth S 1 and S 2 are wrong

Correct answer

A. S 1 is wrong and S 2 is correct

Step-by-step solution

Conductivity changes with the concentration of electrolyte. The number of ions per unit volume carrying the current decreases on dilution, so conductivity (K) always decreases with decrease in concentration. Molar. Conductivity increases with dilution. ∧ m molar   conductivity = 1000 × K C
