What Is One Way You Could Witness A Chemical Property

How are chemical properties witnessed?

Chemical Property Examples

Chemical properties can only be established by changing a substance’s chemical identity and are different from physical properties which can be observed by viewing or touching a sample. The internal qualities of a substance must be altered to determine its chemical properties.

How do you identify a chemical property?

A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property we look for a chemical change. A chemical change always produces one or more types of matter that differ from the matter present before the change.
