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. WebPotassium hydrogen tartrate (KHT) KHT is the most common crystalline deposit found in wines. It occurs when bitartrate ions (HT-), formed by the dissociation of tartaric acid, precipitate out with potassium ions. The characteristic boat or lens-shaped morphology of these crystals is shown here.

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%). Le dianion tartrate est l'ion de formule brute C4H4O6 et semi-développée OOC-(CHOH)2-COO . C'est la base conjuguée de l'acide tartrique, un acide dicarboxylique : l'acide 2,3-dihydroxybutanedioïque, ou acide 2,3-dihydroxy succinique.

Juice is typically supersaturated with potassium bitartrate at crushing. As the alcohol content rises during fermentation, the solubility of bitartrate decreases. This induces the slow precipitation of potassium bitartrate (cream of tartar).
