Abstract
A silver reference electrode is constructed from a plastic transfer pipet using Soil Moist as a salt bridge. The potential difference between this electrode and a silver wire placed in a reaction mixture containing Ag+ is measured. Reagents are added successively that reduce the silver ion concentration. The potential measurements can be used to compute approximate solubility products and stability constants for the successive reaction products.
