Difference Between Sodium Carbonate & Calcium …

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.
