Web4 sep. 2024 · After 3000 min, the pH drops further and the adsorption of oxalate ions increases to 41%. The course of adsorption of tartrate ions after changing the pH of the suspension from 7.2 to 9.9 is similar to that of oxalate ions. However, the decrease in adsorption is smaller than for oxalate ions (adsorption reduces from 83.5% to 64%). Web1 jan. 1984 · In all cases the tartrate ion has its chain of carbon atoms almost exactly in a plane and the C-C02 groups constituting each half of the ion are also practically planar. The planes of C-C02 groups are inclined nearly at 60 to the plane of the carbon atoms. C2 symmetry has therefore been assumed for a tartrate ion in aqueous solution.
