Chemical changes indicators are substances that change color, temperature, or another physical property when a chemical reaction occurs. These indicators allow chemists to identify and predict the occurrence of a chemical change.
The most common chemical indicators are based on indicators that undergo a physical change, such as pH indicators, starch indicators, and litmus indicators. These indicators change color based on the pH of the solution they are added to, indicating whether it is acidic, basic, or neutral.
Another type of indicator is based on indicators that undergo a chemical change, such as phenolphthalein, starch, and iodine. These indicators turn a different color when exposed to chemicals like acids, bases, or oxidizing agents.
Indicators are used in various chemical experiments and in industrial processes to monitor and control chemical reactions. They are essential for the safe and efficient operation of chemical plants and research facilities
