A chemical property
is any of a material's properties that becomes evident during, or after, a chemical reaction
; that is, any quality that can be established only by changing a substance's chemical identity
. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure
must be affected greatly for its chemical properties to be investigated. When a substance goes under a chemical reaction, the properties will change drastically, resulting in chemical change
. However, a catalytic
property would also be a chemical property.
