Neutralizing hypochlorite with ascorbic acid.

[Azur]

Ascorbic acid, like sodium thiosulfate, is sometimes used to reduce hypochlorite (and chloramine, and dissolved chlorine gas) in drinking water.

However, I'm having a hard time finding out what the actual reaction between ascorbic acid and hypochlorite (and chloramine etc) really is.

Can someone help?

In both cases ascorbic acid (C₆H₈O₆) is oxidized to dehydroascorbic acid (C₆H₆O₆).
For example with potassium hypochlorite:
C₆H₈O₆ + KClO = C₆H₆O₆ + KCl + H₂O
