Hi,

Sorry for the multiple posts.

I read that sodium ascorbate is used in combination with CuSO4 to generate Cu(I) in situ. I was wondering how it does so, is it by donating electrons via its ascorbate hydroxyl groups and kicking off the sulfate to generate NaSO4?

Thanks in advance,

Nescafe.

Ascorbate can undergo single electron transfers - google ascorbyl radical (this is why vitamin C is an antioxidant).

NaSO4?

Not quite...
