Question

how electrodes work in ph meter ?​

Answer 1

Answer:

The combination or pH electrode measures the difference in potentials between the two sides in the glass electrode. To measure the potentials it must be a closed circuit. The circuit is closed through the internal solutions of the electrode and the external solution that is being measured and the pH meter.

Answer 2
