Multiple Choice

When using chlorine disinfectants, lower temperatures favor the formation of _______. Lower temperatures also show _______ to persist somewhat longer.

Explanation:
Lower temperatures push chlorine into the HOCl form, which is the more effective disinfectant. At the same time, the cooler conditions slow chemical reactions, so the free chlorine residual tends to persist longer in the water. So the best pairing is HOCl for the formation and chlorine residuals for the persistence.
