WebThe stability of wine with respect to KHT precipitation can be predicted on the basis of the concentration product (CP). This is calculated from the concentrations of potassium, tartaric acid (total tartrate), pH and alcohol in the wine, using the following formula: CP KHT = ( (Potassium, mol/L) x (Tartaric acid, mol/L) x (% bitartrate ion))/100. WebElectrodialysis: a charged membrane removes selected ions; can remove both potassium and calcium ions (and, to a lesser extent, tartrate ions). Ion exchange: replaces potassium and calcium ions with hydrogen and sodium ions, which will not drop out of solution. lg ice maker slow

WebSeven complex metal antimony tartrates have been synthesized in single crystal form by slowly evaporating aqueous solutions of potassium antimony tartrate (tartar emetic) and divalent metal nitrates or perchlorates. Crystal structures of these compounds all contain infinite chains formed by linking antimony tartrate dimers with divalent metal ions. … 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. WebLe dianion tartrate est l'ion de formule brute C4H4O62− et semi-développée −OOC-(CHOH)2-COO−. C'est la base conjuguée de l'acide tartrique, un acide dicarboxylique. On appelle aussi tartrate un sel ou un ester de l'acide tartrique. Le sel le plus commun est le (2R,3R)-bitartrate de potassium, un énantiomère présent dans le raisin et le vin. lg ice maker works intermittently
