AI Thread Summary
The discussion focuses on simulating a pool system with specific concentrations of cyanuric acid and chlorine. The user is trying to determine how to incorporate a chlorine concentration of 125g/L into a 1ppm solution for dilution. They calculate the volume needed for the chlorine using the equation C1V1=C2V2, arriving at a volume of 0.0134mL for the desired concentration. However, there is confusion regarding the total volume of water needed for the pool and the amount of chlorine available. The thread emphasizes the need for clarity on the initial conditions and calculations for accurate simulation.

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.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
