Titration curve 160 wire

Automated titration system For example, Metrohm SM-Titrino 702, with subdivision of 0.005 mL connected to a combined Ag/AgO electrode. It is also possible to plot the titration curve by measuring the potential ( ) with a digital voltmeter using two silver wires as electrodes one placed in the burette Le., in dUute AgNOs solution) maintaining a constant potential and the other wire is immersed in the seawater sample (as the AgQ electrode). This electrode must be cleaned from time to time. 

B. The apparatus in the figure above can follow the course of an EDTA titration and was used to generate the curves in Figure 12-9. The heart of the cell is a pool of liquid Hg in contact with the solution and with a Pt wire. A small amount of HgY2- added to the analyte equilibrates with a very tiny amount of Hg2+ ...
