SUMMARY

The discussion centers on converting iodine concentration ([I2]) to hydrogen ion concentration ([H+]) in a chemical reaction context. The user seeks to determine the time required for [H+] to reach 0.15 mol/L, given a graph of [I2] concentration over time. Participants suggest using a line of best fit to analyze the graph and emphasize the stoichiometric relationship between [I2] and [H+], noting that one mole of I2 produces a specific amount of H+. The importance of understanding reaction rates and the initial concentration of [H+] is also highlighted.

PREREQUISITES
  • Understanding of stoichiometry in chemical reactions
  • Familiarity with concentration units (mol/L)
  • Ability to interpret graphs and perform linear regression analysis
  • Knowledge of reaction kinetics and rates
NEXT STEPS
  • Learn how to perform linear regression analysis on experimental data
  • Study the stoichiometric relationships in chemical equations
  • Explore the concept of reaction rates and their calculation
  • Investigate the effects of buffering on pH and concentration changes
USEFUL FOR

Chemistry students, educators, and researchers involved in chemical kinetics and concentration analysis will benefit from this discussion.

Homework Equations

The Attempt at a Solution


I need to know the time it takes for the [H+] concentration to be 0.15mol/L. However, the graph gives me the [I2] concentration over time, and I don't know how to convert it to the [H+] concentration. How should I solve the problem? Thanks!

Why would you want to do that ?

I meant how to convert the known [H+] concentration to the [I2] concentration given to me by the graph. Because I need to know the time it takes for the hydrogen to reach the 0.15 mol/L concentration right?

I don't really understand what the question is, nor your answer.
[H+] = 0.015 mol/L at t = 0 aren't you told? It takes no time to get there.
The reaction rate looks to be constant. Have you tried to draw a straight line through it, or a least squares fit?
What do you understand by relative rate?
The chemical equation is telling you one mole of I2 that reacts produces how many moles of H+? Added to the store to number it is easy to know how many starting number it is easy to know how many m moles/L there are after any amount of reaction. Though whether this is relevant depends what the question is.

Oh I think I understand it now! I just need to draw the line of best fit and find the gradient of that line. Thanks!
 
The way the problem is worded I suppose the solution was buffered and pH was constant.

I impliedXvideos Youporn Xhamster how to change over the known [H+] focus to the [I2] fixation given to me by the chart. Since I have to know the time it takes for the hydrogen to achieve the 0.15 mol/L focus right?
