Question about SN diluted in water

[Defatigatis]

I was wondering: if i dissolved SN in water, how long would it remain effective? Does anyone have any information about this?

Assuming I were traveling for an indefinite period of time and kept some water mixed with SN with me, would it still be viable to drink?

Ai says that a diluted SN in water should be good for a few days if the container in which the solution is it's tightly sealed. But im not sure, i dont trust Ai so much. I would like to know the answer to this question too.
