The solubility of calcium carbonate was also measured at pH 7.5 6.0 and 4.5 with two CO(2) environments (0.3 and 152 mmHg) above the solution. The precipitation profile of CaCO(3) was calculated using in-vivo data for bicarbonate and pH from literature and equilibrium calculations. As pH increased the solubility of each calcium salt increased.

Cliquez pour discuterPrecipitated calcium carbonate (PCC) is produced by precipitating a calcium salt out of a solution under defined conditions. Normally a filtered solution of calcium hydroxide Ca(OH)2 (from burnt lime) is used as the calcium source. This must not contain any colored impurities. Calcium carbonate is precipitated by the admixture of gaseous carbon dioxide or sodium carbonate Na2CO3.
Cliquez pour discuter· Antacids work by counteracting (neutralising) the acid in your stomach. They do this because the chemicals in antacids are bases (alkalis) which are the opposite of acids. A reaction between an acid and base is called neutralisation. This neutralisation makes the stomach contents less corrosive.
