Well, pAg and pX are related of course...
and while pAg is of interest, is it not the AgX solublity that is really the important consideration when conductivty is being measured, ie just prior to CD?

If so, then the halide concentration should be of interest... in anycase you are right, conductivity is not really a measure of either pAg or pX,
but... they both change with progressive wash efectivness and therefore their former? usefulness as a guide.

On no, lets wait a while!
