Abstract

So long as the mixture remains yellow and there is no visible precipitation of silver chromate, the contact potential remains the same as that of silver in silver nitrate of the same concentration as in the mixture ; but with the appearance of the precipitate, the contact potential gradually decreases and tends towards a limiting value. The general conclusions from the measurements of contact potential can be summarised as follows:(1) More than 95 per cent of the silver chromate remains in the ionic condition in the gel.
