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.

∙ 12y agoindicators are substances which indicates the end point....it may by appearance or disappearence of colour....it s because of the chromophoric area present in the compound formed by the reaction and the auxochrome decides the intensity of colour

What are indicators made of?
It depends on what sort of indicators. Some of these are: visual indicators, made mostly of plastic and glass, which are visual signs of a machine being on, or the direction in which a car is going to turn; chemical indicators that take on a specific colour in the presence of other substances; economic indicators, derived from various data, that show the level of economic activity;
How do you know when there is No Reaction in a chemical reaction?
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

Which are 4 indications of chemical reaction has occurred?
The indicators of a chemical reaction are :- 1. Change in colour 2. Change in temperature 3. Evolution of a gas 4. Formation of a precipitate
Which of the following is a definite indicator that a chemical change has occured?
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)
If you are trying to decide whether a chemical reaction does or does not take place when two substances are mixed what kind of evidence will you look for?
change of state change of colour fizzing/gas bubbles
What do indicators tell us?
Indicators are used to tell a person whether or not a chemical is present or what pH a substance may be. Usually an indicator is a strip that is dipped into the substance and will change color based on the presence of a substance or pH.
Why indicator change color?
Indicators are mostly organic aromatic compounds in acidic to basic medium or vice versa the resonating structures of indicators become change which are responsible to change the colour.
What are three indicators of a chemical reaction occurring?
there are mainly two ways that indicate that a chemical change has taken place. These ways are the physical properties (the way things look, without changing the chemical makeup of a substance) are different, and the chemical properties (the way the substance reacts with other substances) are different.
Indicates how likely an element is to undergo a chemical 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 - formation of new compounds
