Distinguished between salt - calcium carbonate and copper carbonate
Answers
Answer:
The carbonate ion (CO3) 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 (Na2CO3) and calcium carbonate (CaCO3). 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. Both are very common compounds. Although calcium carbonate, which comprises 4 percent of the earth's crust, is the winner in this category. Both are white powders with many uses, but they have some key differences.
Answer:
Calcium Carbonate
1. Calcium Carbonate is a chemical compound with the formula CaCO₃.
2. It is a white precipitate formed when carbon dioxide gas is passed through lime water.
3. In water and sewer treatment plants, calcium carbonate is employed in the removal of acidity and impurities.
Copper Carbonate
1. Copper Carbonate is a chemical compound with formula CuCO₃.
2. Copper carbonate is green in colour.
3. They are used as a pigment in products, paints, and varnishes.
