Simulating a pool system - concentrations help

  1. Nov 5, 2012 #1
    1. The problem statement, all variables and given/known data
    For part of my course I have to simulate a pool. In the pool there will be a 40ppm solution of cyanuric acid, a 1ppm solution of chlorine (sodium hypochlorite) and a buffer (i have no idea of the compound so its moot trying to figure it out)
    I have been given a figure of 125g/L of availible chlorine. The question is how do i incorporate this into my concentration needed; but more importantly, is my volume of chlorine correct for the dilution?
    (C1 and V2 are 1 mole and 1000mg/L respectively

    2. Relevant equations



    3. The attempt at a solution[/]
    C1V1=C2V2
    1ppm of sodium hypochlorite in moles is .001/74.442 =1.34 x 10^-5 approx
    thus V1= 1.34 x 10^-5 x 1000
    thus V1 = 0.0134mL

    1 ppm = 1 mg/L
    Given 125 ppm
    Wanted to be reduced to 1 ppm
    You have no data of the amount of Chlorine, e.g. 1L, you have and the amount of water you need in the pool...

    I 500ml of chlorine. I need 1 litre of water. I just need to make a stock solution of 1ppm of chlorine to add to 1 litre of distilled water.
