A resort has a swimming pool that is kept at 25â¦C and a hot tub that is kept at 40â¦C.
The water in both facilities contains 2Ã10^â4 M total hypochlorite (TOT OCl, the sum of
the HOCl and OClâ concentrations) and is adjusted to pH 7.2 (aH+ = 10^â7.2).
(a) The equilibrium constant for the dissociation of HOCl into H+ and OClâ in the swimming pool
is 10^â7.53. What is its value in the hot tub?
(b) What is the concentration of HOCl (the more powerful of the two disin-fectant species)
in each solution, if the solutes behave ideally?
