Indicators are chemical solutions that are used for the main purpose of showing whether the tested solution is an acid or base. That being said indicators can be acids or bases.
What is an emample of a chemical change?
The following are indicators of chemical changes: ... For example, changing the color of a metal does not change its physical properties.
What characteristics limit the usefulness of indicators?
Chemical indicators measure the pH directly Chemical indicators are highly expensive They must be chosen for a specific pH range Chemical indicators cannot determine the exact value of pH of the solution
What are indicators of a chemical change when 2 substances are mixed together?
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.
