Les détergents à base de carbonate ont un usage limité dans les usines de transformation des aliments parce qu'ils interagissent avec le calcium et le magnésium pour former des composés hautement insolubles. Les silies sont souvent inclus dans les détergents pour inhiber la corrosion. Les PTS sont bien connus pour leur efficacité ...
· Calcium carbonate . Calcium carbonate is one of several abrasive agents that help clean teeth and remove stains. You might even see stains reduced in a matter of days, Hewlett says. "Widely used abrasives like calcium carbonate are mild and can be used safely with prudent brushing," but brushing too hard with any toothpaste can damage teeth, he ...
The main use of calcium carbonate is in the construction industry, either as a building material, or limestone aggregate for road building, as an ingredient of cement, or as the starting material for the preparation of builders' lime by burning in a kiln. However, because of weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on ...
Calcium carbonate: H 2 T + CaCO 3 → (↓) + H 2 CO 3 The above precipitation reactions only occur with tartaric acid salts, as the potassium and calcium salts of malic acid, for example, are soluble in wine and the precipitation of the socalled 'double salt' (double tartromalate salt) is only possible above pH (RibéreauGayon et al. 2006).

L'élimination du carbonate de calcium est réalisée par attaque chlorhydrique 1 N jusqu'à disparition complète de l'effervescence. Puis l'acide et le sel sont éliminés par lavages successifs. Nous verrons dans les chapitres suivants que ce traitement peut provoquer des déséquilibres au niveau des isotopes du strontium de certains minéraux argileux. Le sulfate de calcium est éliminé ...
· Calcium carbonate reacts with hydrochloric acid to form calcium chloride, water and carbon dioxide. The reaction between these two compounds requires two parts hydrochloric acid to one part calcium chloride. This reaction is fairly rapid and energetic at high concentrations, in large part due to the high affinity of calcium ions for chloride ions.
