I’m doing an investigation on how temperature affects vitamin C content, could you please tell me if a standard solution of ascorbic acid should degrade with increasing temperatures, from 40 °C to 90 °C. How do I calculate the concentration of vitamin C?
Igloo writes ...
I should think that there is a good chance that a standard solution will slowly degrade at higher temperatures, and since this solution needs to have a reliable and fixed concentration, heating it up is not a good idea.
As to your second question we have a fairly comprehensive tutorial here Vitamin C investigations
and this includes a discussion on the calculations involved.
Always carry out a risk assessment and check with your teacher before starting any practical work.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
