Equilibrium System: Experiment 5 - Study of Chromate/Dichromate Ions

[kaleykmytarvt]

Hey everyone!
I am new here and I need MAJOR help on an experiment. It's grade 12 university prep Chemistry course that I am doing via correspondance. Basically I have read through equillibirum notes (Like 20 pages worth and I am VERY confused). I get the basic idea but am still haveing a tough time-I have this simulated lab and I need help. It is rather long but I was wondering if someone has done this lab before or if they were willing to help me work through it ...?
The experiment is called: "Experiment 5: A study of an equilibrium system"
and the purpose is to study the varying concentrations of the hydrogen ion on the equilibrium system for chromate/dichromate ions.

Please let me know if anyone is interested in helping me--It has been quite a while since high school chem so be patient with me

I will post more info if someone is willing to help

Dear student,

I am happy to help you with your experiment on the study of chromate/dichromate ions. Equilibrium systems can be complex, but with the right guidance, you will be able to understand and complete this experiment successfully.

Firstly, it is important to understand the concept of equilibrium in a chemical system. In simple terms, equilibrium is a state in which the forward and reverse reactions occur at the same rate, resulting in no net change in the concentrations of the reactants and products. In your experiment, you will be studying the equilibrium between chromate and dichromate ions, which involves a redox reaction.

To begin, make sure you have a clear understanding of the experiment's purpose and the concepts of redox reactions and equilibrium. Next, carefully read through the instructions and materials provided for the experiment. It is also helpful to draw a diagram of the experimental setup to visualize the process.

In this experiment, you will be varying the concentration of the hydrogen ion, which is a key component in the equilibrium system of chromate and dichromate ions. As you change the concentration of the hydrogen ion, the equilibrium will shift to maintain a balance between the reactants and products. This will allow you to observe the changes in the color and concentration of the solution, which can be used to determine the equilibrium constant, Kc.

To obtain reliable results, it is important to follow the experimental procedure carefully and accurately measure the concentrations of the solutions. Remember to record all your data and observations in a clear and organized manner.

If you encounter any difficulties during the experiment, do not hesitate to reach out for help. You can consult your notes, textbook, or online resources for additional explanations. It is also helpful to discuss the experiment with your peers or a teacher to gain a better understanding.

I hope this helps you with your experiment. Good luck!
