Things that can indicate a chemical change has occurred include
In chemical changes, the composition of the substance changes, and it is often difficult to reverse the process.
Some indicators of a chemical reaction are:
- change of color
- change of odor
- release of a gas
- change of the temperature
- change of the viscosity
- formation of a precipitate
- change of general appearance
- possible explosion
- possible chemiluminescence -formation of new compounds

Gas formation, solid formation, energy release, and/or a color change.
Heat, formation of a gas, formation of a solid, color
color change
heat or light
the change is difficult to reverse
precipitate or gas forms
temperature change, formation of a solid from two aqueous solutions, gas formation, color change
Not all reactions will have all of these indicators.
No, a chemical change. Taste and smell are indicators of chemical composition, so a change in those would indicate a chemical change.
To indicate the change of its Ph nature either from acid to a base or a base to an acid
Precipitate (solid matter formation), Temperature change, Gas formation, and color change.
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence
Any chemical change within any product is due to the ph level that the product carries. Chemical changes occur when you mix one thing with another. Most things you mix together will cause a reaction but it all depends on if the product is an acid or not.
No, a chemical change. Taste and smell are indicators of chemical composition, so a change in those would indicate a chemical change.
The following are indicators of chemical changes: ... For example, changing the color of a metal does not change its physical properties.
Some indicators include:Change in TemperatureChange in ColorNoticeable Odor (after reaction has begun)Formation of a PrecipitateFormation of BubblesWhen two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed. Proceed with caution.
indicators of a chemical reacton include color change, heat given off, and gas produced. indicators of a physical change are phase changes, changes in shape, and changes in size. "Being blue" is not a change at all. It's a condition.
To indicate the change of its Ph nature either from acid to a base or a base to an acid
Definite indicators of a chemical reaction include exothermic reactions (heat), colour change, bubbles and there might be a few morea new substance forms (study island)
