The conductivity of an acid solution depends on the?

A. amount of ions present and their mobilities
B. mobilities of the ions present
C. amount of ions present
D. temperature of the solution

Correct Answer:

Option A – amount of ions present and their mobilities

Explanation

The conductivity of a solution depends on the number of charge carriers (the concentrations of the ions), the mobility of the charge carriers and their charge. Theoretically, conductivity should increase in direct proportion to concentration.
