What is Chemical identification test of lithium carbonate?

One common chemical identification test for lithium carbonate is the flame test. When lithium carbonate is heated in a flame, it produces a characteristic crimson red color. This color is distinctive for lithium ions and can be used to confirm the presence of lithium in a sample.


What is the blood red residue formed in a glass test tube when copper carbonate is heated vigourously with carbon?

Elemental copper.


What happens to the falme when th burning splint is put into the mouth of the test tube with the test tube of solid calcium carbonate in it and then heated?

The burning splint is extinguished by the carbon dioxide given off from the calcium carbonate. CaCO3 --heat--> CaO + CO2 ==================================================


How do you test for carbonate ions?

1) Add a little hydrochloric to acid to a sample of the solid or solution you wish to test for carbonate ions 2) If effervescence is seen & the gas produced turns limewater milky white, the gas produced was carbon dioxide - this indicates that carbonate ions were present


How can you test strontium nitrate ammonium carbonate and potassium sulfate?

To test for strontium nitrate, you can perform a flame test which will produce a red flame color. For ammonium carbonate, it will release ammonia gas when heated and form a white precipitate when reacted with a sodium hydroxide solution. Potassium sulfate can be identified by its solubility in water, as it is highly soluble.


Why Na2Co3 extract is not used for carbonate test?

Na2CO3 extract is not used for carbonate test because it is a carbonate compound itself (sodium carbonate). Using it in the test would not provide a valid result, as it would already contain carbonate ions. To test for carbonate ions, a substance that does not already contain carbonate, such as hydrochloric acid, is used.


What does the acid test tell you about a mineral?

The acid test is used to determine if a mineral contains carbonate minerals. When a mineral fizzes or reacts with acid, it indicates the presence of carbonate minerals such as calcite or dolomite. This test helps mineralogists identify and distinguish between different minerals.

What test could you do to see if there is Sodium Carbonate Gas?

Sodium Carbonate is not a gas it is a solution. I think you mean how can you test for Carbon Dioxide - bubble it though limewater and you will get Sodium Carbonate.

How can you distinguish calcium carbonate from other deposits?

You can distinguish calcium carbonate from other deposits by performing a simple acid test. Calcium carbonate will effervesce (bubble and release carbon dioxide) when treated with a weak acid such as vinegar. This reaction is specific to calcium carbonate and can differentiate it from other mineral deposits.
