Abstract
AMPHOTERIC electrolytes are those which are capable ¦“of acting as acids towards bases and as bases towards acids. One of the simplest types is that of the amino-acids, for example, glycine, NH2.CH2.COOH, which in virtue of the NH2 group is an anhydrous base, whilst in virtue of the COOH group it is an ordinary organic acid. When such a substance is dissolved in water, it is ionised as acid, as base, and as the salt formed by their reciprocal neutralisation. From molecular weight determinations in aqueous solution it is found that in general the molecule is simple and not double, so that the unionised salt must be
