What does a chemical property give a substance the ability to do?
A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.
When examining the physical properties of an unknown substance characteristics is unsafe to observe?
This depends on the nature of this substance; precautions are necessary.
Why is it important to identify an unknown substance?
Because the substance could potentially be extremely toxic or harmful. You must never use an unknown substance in experiments without identifying it first, many tests can be undertaken to determine the cation and anion. These tests include the flame test, solubility tests, precipitate reaction tests and conductivity tests. These do vary depending on the unknown substance.
What is meant by a characteristic property of a substance?
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
What can be used to identify an unknown substance?
Just about any property that can be observed or measured can help you reduce the number of options.
