does a color change indicate a chemical reaction

Best answer


A color changemay also indicate that a chemical reaction has occurred. A reaction has occurred if two solutions are mixed and there is a color change that is not simply the result of a dilution of one of the reactant solutions. A color change may also occur when a solid and liquid are mixed.

  • What is color change chemistry?

  • Color change chemistry isn’t restricted to chemical solutions. Chemical reactions produce interesting colors in flames, too. Colored fire spray bottles may be the most popular, where a person sprays a solution toward a flame, changing its color.

  • What determines the color of a substance?

  • The properties of a substance which determine its color are chemical properties (the color is determined by the optical properties which are largely determined by the bonding interactions). Therefore a change in color is indicative of a change in bonding, which is a chemical change.

  • Why doesn’t the colour change when the concentration of a compound increases?

  • Since this gives an overall increase in the concentrations of both chemicals, neither has increased relative to the other, and the equilibrium position hasn’t moved, so the colour doesn’t change. equilibrium Share Improve this question Follow edited May 15 ’17 at 21:40
