hey friend
Whenever a chemical change occurs we can say that a chemical reaction has taken place. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is occurring.
hope this may be the correct answer for ur question!!
