There is not a direct relationship between conductivity and pH, unless the solution is in ultrapure water, and the same species is responsible for both the increased conductivity and the pH change.

Does electricity affect pH?

In addition to adding an acid or a base to water, the pH can be changed by electrolysis. ... You will track the changes in the pH values over time. Water can be decomposed by passing an electric current through it. At the negative electrode, electrons from a battery are added to the water molecules.

Can you calculate pH from conductivity?

An accurate pH value can also be obtained by measuring the conductivity before and after a strong acid ion exchanger. These measurements are used to calculate the pH. ... This type of measurement, which is commonly used for feed water and boiler water, is very popular in Europe.
