WebCatalyse par l’ion cobalt (II) La réaction chimique lente entre les ions tartrate et l’eau oxygénée est catalysée par l’ion cobalt (II). Sans catalyseur, la réaction chimique est lente, même avec un léger chauffage. Dès l’ajout de catalyseur, la réaction s’accélère, produisant un dégagement gazeux notable. 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.
