AI Thread Summary
The discussion centers on an investigation into the chlorine content in bottled and tap water for a chemistry class project. The initial approach involved using silver nitrate to react with chlorine, but concerns were raised about potential interference from other chemicals in the water. After further consideration, it was determined that conducting this experiment might not be feasible in the school laboratory. Consequently, the experiment was changed to a more suitable alternative that could be performed within the school's resources. The conversation highlights the challenges of experimental design in educational settings.

Hey its me again and I am just hoping for a few comments on my work on an investigation were doing in chemistry class about common drinks and additive in them. I've decided to do Water and Chlorine in the water to investigate how much chlorine is in water bottled and tap. My thoughts are that if i get a substance that will be more attractive to chlorine than the other chemicals in water bonding with the chlorine and if i make a formula on the reaction i can figure out how much chlorine there is by how much of the substance reacts with the chlorine. My original thought was silver nitrate, as i read it in my chemistry textbook but on the internet it says that the silver nitrate will react with only with a Compound including chlorine to form a percipitate, i think it was calcium chloride ill go back and find it. But anyway I am not sure if it'll work because the silver nitrate might mix with some other chemicals in the water. Anyway these are my thoughts so far. Thanks for taking the time reading and any comments will be usefull. Regards Papak

Never mind, its not possible to do in school laborotries that we have, I've changed the experiment to do something more able in our school labs, thanks anyway. Papak

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...
