The resistance of 1 N solution of acetic acid is 250 ohm , when measured in a cell having a cell constant of 1.15 c m - 1 . The equivalent conduction ( in Ω -1 cm 2 eq -1 ) of 1 N acetic acid is .......

Options

  1. A18.4
  2. B9.2
  3. C4.6
  4. D2.3

Correct answer

C. 4.6

Step-by-step solution

K = C × cell constant = C e l l constant R = 1.15 250 ∧ eq = K × 1000 Normality = 1.15 250 × 1000 1 = 4.6 Ω - 1 c m 2 e q - 1 .
