Benedicts reagent to albedo extract

[smhjn17]

I added benedict reagent to the albedo extract from the peel of a citrus fruit and what happened ?.. The solution just turned green without any heating ...what can be the cause ???

Vitamin c?

But how ?

[John Cuthber]

Vitamin c is a strong reducing agent It can reduce Benedict's solution without boiling.

If there's only a little vitamin c then it will produce a little of the yellowish copper oxide and together with the leftover blueish copper salts you get a green colour.
