A pool uses 0.600 M sodium hypochlorite as a chlorine source: NaCl(aq) +H,0 → HOCI (aq) + NaOH(aq) The NaOCI solution flows in at a rate of 1.25 L/min. If the pool has an initial HOCI concentration of 1.00 x 105 M, and the desired HOCI concentration is 1.66 x 10-5 M, how long does it take to reach this desired concentration? The pool has a volume of 23 000 USG, which can be assumed to remain constant. u Nood
