The pH of a solution can be measured using an electronic device called a .

Electrode Potential:

The potential of an electrochemical reaction depends on the concentration of reduced and oxidised species.The change from the standard potential can be calculated with the Nernst equation.For a glass electrode, this results in:E = Ecell - 0.059 x pH VoltsYou find that the potential of a solution with unknown pH is 0.177 V higher than the potential of the calibration buffer at pH 7.What is the pH of the solution? 2 10 4 8 6

What is the source of:(a) the junction potential in a glass-reference electrode system?
