Question : 142

Total: 160

The conductivity of 0.01 M aqueous acetic acid measured with a conductivity cell of cell constant of 0.5 1 cm ‌−1 at 298 K is 3.12×10−4 S . If the limiting conductivities of H ‌+ and CH3COO− at the same temperature are 349, and 41 S cm ‌2 mol ‌−1 respectively, the dissociation constant of acetic acid is

1.67×10−4
1.67×10−5
1.67×10−3
1.67×10−6
