Question

The equivalence conductances of 1N acetic acid

Answer 1

Answer:

The resistance of 1 N solution of acetic acid is 250 ohm , when measured in a cell of cell constant 1.15 cm-1 . The equivalence conductance ( in ohm-1 cm2 equiv-1) of 1 N acetic acid is. a) 4.6. b) 9.2.

Answer 2

Answer:

The equivalent conductance of strong electrolyte sodium chloride at infinite dilution is 136 S cm2 equiv-1 and that of acetic acid is 384 S cm2 equiv-1. The experimentally determined value of dissociation constant, K of acetic acid is 1.87 × 10-5 M.
