Question

How might you go about testing an unknown substance to determine it's chemical properties?

Answer 1

Using chemical tests

Step-by-step explanation:

I will go about testing an unknown substance to determine its chemical properties by carrying out series of chemical tests on it.

Qualitative analysis deals with the determination of the amount or concentration of chemical species in a sample of substance or their chemical reactions with other substances.

• Such test will involve:

1. weighing of the substance
2. heating of a solid in an ignition tube
3. heating a liquid in a test-tube or boiling tube
4. making a solution
5. Purification of the substance

Also reagents are also applied to make some inferences about the nature of the unknown compound.
