Does chlorine lose potency over time?

Can chlorine be stored?
Properly stored chlorine tablets should last three to five years. The storage site should be cool, dry and well-ventilated, such as in a basement. Never leave chlorine tablets in the direct sun, even in a covered bucket, because the heat will accelerate the degrading process of the tablet and its ingredients.
