7.06 -- Equilibrium Lab Report Jamis Bornschein
Instructions: For this investigative phenomenon, you will observe the changes that result when
you add more or take away some of one of the components of the equilibrium and determine if
there are trends in the behavior of equilibrium systems. Record your observation in the lab report
below. You will submit your completed report.
Title: Equilibrium Lab Report
Objective(s): To observe how increasing or decreasing the concentration of one component
of an equilibrium system affects the position equilibrium.
Hypothesis:
If reactants are added the equilibrium will shift towards the right. If reactants are taken
away the equilibrium will shift to the left.
Procedure:
Access the virtual lab and complete the inquiry experiment. List your controlled variables,
independent variable, and dependent variable. Explain why these are the variables. Summarize
the steps of the experimental procedure.
Materials:
Equilibrium Virtual Lab
Variables:
Remember, controlled variables are factors that remain the same throughout the experiment. An
independent (test) variable changes so that the experimenter can see the effect on other
variables. The dependent (outcome) variable will change in response to the test variable.
Controlled variables: Lab Equipment, condition in which reactions are happening
Independent variable: Concentration of the reactants in the product
Dependent variable: Position of equilibrium, color
Include a summary of steps here. We have included the first two important steps to get you
started. You can summarize the rest from the virtual lab.
1. Write down the equilibrium equation you are investigating using the information provided by
the introduction within the virtual lab activity
Equilibrium reaction:
2. Select each control test tube to compare the concentrations of reactants and products. Write
down what each indicator color means about the concentrations of reactants and products in
solution.
Pink means: Increase in aqueous cobalt
Blue means: Increase in CoCl4
Purple means:same amount of CoCl42-and Co (H2O)62
Data:
For each trial, make sure you record the initial color of the solution, what is added to the test tube
(a description of the stress), and what happened after the substance was added.Also include a
screenshot, sketch, or description of each graph of each trial.
