The resistance of solution of acetic acid is when measured in a cell having a ce
The resistance of \( 1 \mathrm{N} \) solution of acetic acid is \( 250 \Omega \) when measured in a cell having a cell constant of \( 1.15 \mathrm{cm}^{-1} . \) The equivalent conduction (in oh \( m^{-1} c m^{2} e q u i v^{-1} \) ) of \( 1 N \) acetic acid is
- A. 2.3
- B. 4.6
- C. 9.2
- D. 18.4
Step-by-step solution
Conductivity κ = cell constant / resistance = 1.15 cm⁻¹ / 250 Ω = 0.0046 S cm⁻¹. Equivalent conductance Λ_eq = κ × (1000 / N) = 0.0046 × 1000 = 4.6 ohm⁻¹ cm² equiv⁻¹.
