SUMMARY

This discussion focuses on an investigation into the chlorine content in bottled and tap water, specifically using silver nitrate as a potential reagent. The participant, Papak, initially considered using silver nitrate to react with chlorine in water to quantify its concentration but later concluded that the experiment was not feasible in a school laboratory setting. The conversation highlights the challenges of conducting chemical analyses in educational environments and the need for accessible methodologies.

PREREQUISITES
  • Basic understanding of chemical reactions and precipitate formation
  • Familiarity with silver nitrate and its applications in chemistry
  • Knowledge of chlorine compounds, such as calcium chloride
  • Awareness of laboratory safety and limitations in school settings
NEXT STEPS
  • Research alternative methods for measuring chlorine levels in water
  • Explore the use of titration techniques for chlorine analysis
  • Investigate the properties and reactions of silver nitrate in aqueous solutions
  • Learn about safe and effective laboratory practices for school experiments
USEFUL FOR

Chemistry students, educators, and anyone interested in water quality analysis and safe laboratory practices.

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
