SUMMARY
The discussion centers on the thermal decay of citric acid during a school experiment involving lemon juice. The experiment involves filtering lemon juice and titrating it against a molar solution of sodium hydroxide while varying temperatures from 10 to 90 degrees Celsius. Key insights indicate that citric acid does not begin to decay significantly until temperatures exceed 148 degrees Celsius. Additionally, the degradation of citric acid can be influenced by factors such as exposure to light, and the method of concentration affects the results.
PREREQUISITES
