Answer: C. A Chemical Change
Explanation:
A chemical change is one that occurs when new substances are produced preceding a chemical reaction ( the mixing or combination of one substance with another).
From the experiment by Jasmine, since light was produced from the mixture, energy is being released which is due to a chemical change.
When you doing a titration, you need to use an indicator to confirm whether the reaction is completed. When the indicator has the color change and will not change back in one minute, the reaction is finished and you don't need to add more.
