How do you identify sodium carbonate?
Compare the color of the pH paper with the pH scale typically printed on the pH paper pack and assign pH of the solution accordingly.
If pH is around 8, the sample is sodium bicarbonate.
If pH is in the range 9.5 to 10, it is sodium carbonate..
What makes something a carbonate?
A carbonate is a chemical compound that has the carbonate ion, CO 2− 3. . This ion is made of carbon and oxygen. The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O–)2 of carbon and oxygen.
How do you test for metal carbonate?
Acids and metal carbonates It can be detected by passing the gas through limewater, which will go cloudy. Also, the reaction of metal carbonates with acids is exothermic (ie heat energy is given out). This type of reaction can be used to test unknown solutions to see if they are acidic.
Is carbonate a solid liquid or gas?
Calcium carbonate (CaCO3) is insoluble, so it is a solid in water. When carbonate combines with metals in the second group of the periodic table, the…
