    homebuilt vAg electrode?

    Hello PE,

    Has there been any progress on the idea of building a workable vAg electrode? Do you know of any references that may discuss how one would be constructed?

    Thanks,

    Bob M.

    Bob;

    The starting point is a high accuracy volt meter with silver electrode(s). You will need more than that. A friend who has been helping me has been otherwise occupied. And, so have I.

    For your use though, 0.1 molar NaBr at 20 deg C will have a vAg of -61.48 mv and a pAg of 11.463

    That is, BTW, 10.289 g/l.

    So, here is a calibration point for you.
