Question

When a small amount of electrolyte is added to an oil-in-water type emulsion, the conductance ______.

Answer 1

When a small amount of electrolyte is added to an oil-in-water type emulsion, the conductance increases.

Explanation:

In an oil-in-water emulsion, water acts as the continuous phase, so adding electrolyte increases the number of ions in the aqueous phase, which enhances the electrical conductivity of the emulsion. Thus, the conductance rises upon the addition of electrolytes to o/w emulsions.
