Vitamin C oxidation with light
« on: August 12, 2017, 07:00:50 PM »

Hey guys,
How does light increase the rate of oxidation of ascorbic acid? I am really unsure.

Any help appreciated.

This is what happens when I type it into Google:

https://www.ncbi.nlm.nih.gov/pubmed/12824256

This is a scholarly reference, for a very specialized application.  You can start with these sorts of references, if you're just curious.  If you have a more complete question, you can narrow down resources so that they're better for you.

That all depends on how reasonable we're all willing to be.  I just want my friends back, except for Cartman, you can keep him.

A lot depends on what detail level you are interested in. Do you know general answer to this type of questions?

Do you know that ascorbic acid is sensitive to light or heat and breaks down with time due to oxidation?

I don't really know.

As much information will be good! (Just not too complicated).

In general it is always about molecules being excited by the radiation - when they are excited they are often more chemically active (require lower activation energies) and thus they react easier with whatever is available.
