Re: stability of sodium hypochlorite

[Sebastian Fettig <Sebastian.Fettig@UNI-BAYREUTH.DE>]

I'm wondering why Roth doesn't give values below 20°C since
most of the people I know store hypochlorite solutions at 4°C.
Using an exponential regression from the values given, the
loss of active chlorine at 4°C is 0.2 g/l or 6 mmoles/l. This
means that after one month there still is 90% of the chlorine
present.

If your colleague doesn't use very old hypochlorite solutions or
stores them warm I don't think the decomposition is the
problem.

All the best

Sebastian
