Measurement of the coonductivity of elec...

Measurement of the coonductivity of electrolytic solutions is done with the helpof Wheatstone bridge using a/an

battery

induction coil

conductivity cell

both (2) and (3)

Text Solution

Verified by Experts

The correct Answer is:

Induction coil, an alternating current `(A)` source of power is used to nullify the electrolysis of the electrolyte while conductivity cell is used to connet the electrolytic solution to the bridge like a matallic wire or other solid conductor. Galvanometer is replaced by an earphone bacause when `AC` source is used, ordinary galvanometer fails to detect the null point.
