Difference Between Sodium Carbonate & Calcium .Deze pagina vertalen

19-4-2018 · The carbonate ion (CO 3) has a valency of -2 and forms compounds with sodium (Na), which has a valency of +1, and calcium (Ca), which has a valency of +2.The resulting compounds are sodium carbonate (Na 2 CO 3) and calcium carbonate (CaCO 3).The former is known as soda ash or washing soda, and the latter, known as calcite, is a primary component of chalk, limestone and marble.

Calcium Carbonate - an overview | ScienceDirect .Deze pagina vertalen

The solubility of calcium carbonate in water is very low, e.g., below 1 gram per litre at 20 °C under 1 atmosphere CO 2 pressure. Its solubility is strongly influenced by partial pressure of CO 2, temperature, and concentration of other salts in solution.Changes in super saturation and hence precipitation and scaling usually occur as a result of temperature increase or pressure decrease ...
