Antimony Electrode

Since the electrode potential of antimony metal is a function of the pH of the soil (or solution) that the metal is contacting, a measure of the soil (or solution) pH level can be obtained by determining the potential difference (voltage) between an antimony electrode and a second electrode of known “fixed” electrode potential.

The etched scale on the side of the Antimony Electrode allows the electrolyte (soil or solution) pH level to be assessed based on the potential difference measured between a copper/copper sulfate reference electrode and the Antimony Electrode.

The Antimony Electrode is supplied with operating instructions regarding how to perform a potential difference reading and how to determine the pH level of the soil (or solution) under test (please click on the “Instruction Manual” for information).

Note: The copper/copper sulfate reference electrode (such as an RE-5C Electrode) is required for the potential difference test is not included and would have to be purchased separately.
