under certain Water conditions, the free chlorine (hypochlorous acid, HOCI) in a swimming pool decomposes according to the law of uninhabited decay. after shocking a pool, the pool boy, Geoff, tested the water and found the amount of free chlorine to be 2.4 parts per million (ppm). 24 hours later, Geoff tested the water again in from the amount of free chlorine to be 2.1 ppm. what will the reading after two days (that is, 48 hours)? when the chlorine level reaches 1.0 ppm, Geoff must shock the pool again. how long can just go before he must shock the pool again?
