Which is most often used in the laboratory to measure pH?
A)a standard hydrogen electrode
B)a glass electrode
C)a Daniell cell
D)a conductivity cell

Question

Quizplus · Accepted Answer

A glass electrode is most commonly used in the laboratory to measure pH. It consists of a thin-walled glass bulb filled with a buffered solution and a reference electrode. When the bulb is immersed in an aqueous solution, the pH of the solution can be measured based on the electrical potential of the electrode. The other options listed (standard hydrogen electrode, Daniell cell, conductivity cell) are not typically used to measure pH.
