✦ Synopsis

In previous papers, some mathematical expressions for compleximctric backtitrations of mixtures of metals have been derived ~ and conditions for the possibility of sharp potentiometric end-point indication in the case of indication by means of the titrant have been discussed'-'.

Another method of potentiometric end-point indication is the method based on the addition of an indicator ion, e.g. mercury(II) or silver(l). Conditions for sharp endpoints with this indication method are derived in the present paper, and some experimental applications are presented.
