No, it is NOT an indicator of a chemical reaction. Change in color IS an indicator of chemical change, though.

What is an indicator of a chemical reaction?
HEAT, Heat is the the number one indication of a reaction. Also, changes of state of matter and mass are also indicators of a chemical reaction. an example is when an iron fence rusts.
What happens to total amount of mass in chemical reaction?
The mass remains conserved... while it is in case of a nuclear reaction where the total mass changes... in chemical reaction there is no change in mass...
What happens to the total mass of substances during a chemical reaction?
During a chemical change,chemical energy may be changed to other forms of energy.other forms of energy may also be changed to a chemical energy.
In a chemical reaction the total mass of the substances before the reaction is?
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
How do physical and chemical changes affect mass?
law of consevation of mass states that the total mass before a chemical reaction is the same as the total mass after the chemical reaction
Why isn't a change in mass an indicator of chemical change?
A change in mass is not always an indicator of a chemical change because mass is conserved in chemical reactions. The total mass of the reactants is equal to the total mass of the products. However, there are some exceptions where a change in mass can occur due to the release or absorption of gases or changes in the physical state (such as evaporation or condensation) during a chemical reaction.

What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
How does law of the conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
When is a reaction considered chemical?
When the only change in mass is converted to light. The amount of matter after the reaction does not change.
What happens to total amount of mass in chemical reaction?
The mass remains conserved... while it is in case of a nuclear reaction where the total mass changes... in chemical reaction there is no change in mass...
Which observation does not indicate that a chemical reaction has occured?
Change in total mass of substances.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Which is supported by the law of conservation of mass?
During a chemical reaction, the total mass of the system cannot change.
Where is the mass to a chemical reaction found?
A hemical reaction has no mass; only chemical compounds have molar mass.
What happens to the total mass of substances during a chemical reaction?
During a chemical change,chemical energy may be changed to other forms of energy.other forms of energy may also be changed to a chemical energy.
In a chemical reaction the total mass of the substances before the reaction is?
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
