Abstract
Ga reacts stoichiometrically with complexon at pH 1,8 - 3,5 only on heating. At pH 2,5 - 4 the reaction proceeds in the cold. The colour change is the sharpest at pH 2,8 - 3,5, regardless of the solution temperature. Details are given for the analysis in the presence of Al, Fe, Zr, Th, Ti, V, Pb, Bi, Cu, Sn, and Mo.
