Inside of a chlorinated swimming pool is a delicate balance of hypohlorous acid (HOCl) which is an active disinfectant. Another method of disinfection is the reaction of chlorine gas and the water. Calcium hypochlorite, Ca(OC)2 can also be used as a disinfectant. The pH balance is also very important when it comes to maintaining the integrity of the pool. OHCl is plentiful before swimming in the pool, but lessens as it attacks algae and bacteria. The amount in the pool also depends on the pH of the pool. The pH affects the OHCl and this can be seen from the dissociation reaction:
If the pH is low, the OCl- reacts with H+ to create more HOCl to clean the pool and the equilibrium is shifted to the left. If the pH is high, the HOCl will dissociate and the equilibrium shifts to the right. The pH of the pool is related to the amount of OHCl available and makes the acid shift equilibrium.
The article is directly related to the equilibrium shifts studied in class as well as the acid, base and pH levels. The reactions that happen in a pool can be an example that we have already done in class.
