However, eating a large amount of carrots close to bedtime may lead to discomfort or indigestion, which could potentially disrupt sleep.
What do you call a substance which is used to show changes in pH by its change in color?
An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.
What is the purpose of phenolpthalein?
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
