Discussion Overview

The discussion revolves around simulating a pool system with specific concentrations of chemicals, including cyanuric acid and chlorine. Participants are exploring how to calculate the necessary volumes and concentrations for a chlorine solution, particularly focusing on the dilution process and the relationship between different concentrations.

Discussion Character

  • Homework-related
  • Mathematical reasoning
  • Technical explanation

Main Points Raised

  • One participant states the need to simulate a pool with a 40ppm solution of cyanuric acid and a 1ppm solution of chlorine, questioning how to incorporate the available chlorine concentration into their calculations.
  • Another participant clarifies that 1 ppm is equivalent to 1 mg/L and mentions the need for more data regarding the amount of chlorine and the volume of water in the pool.
  • A participant indicates they have 500ml of chlorine and need to create a 1ppm stock solution to mix with 1 litre of distilled water.
  • A repeated post by the same participant reiterates the need to create a 1ppm stock solution from 500ml of chlorine to add to 1 litre of water, suggesting a lack of clarity in the thread.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the necessary calculations and the specifics of the chlorine solution preparation. There is no consensus on the correct approach or the required data for the simulation.

Contextual Notes

Participants have not provided complete data regarding the volumes of chlorine and water, which may limit the accuracy of their calculations. The assumptions about the concentration and volume relationships are not fully resolved.

Who May Find This Useful

This discussion may be useful for students or individuals interested in chemical concentrations, dilution calculations, and practical applications in pool chemistry.

Homework Statement


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

Homework 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.

We are still waiting for a first comprehensible post in the thread.
