Question
  1. Consider the reaction below at equilibrium. The solution is an orange/red color. Note: Thehydrated Cr2O72- ion is orange. Hydrated Cr3+ is violet. All of the other substances are colorless.

Cr₂O₇²⁻₍ₐq) + 3C₂O₄²⁻₍ₐq) ⇋ 2Cr³⁺₍ₐq) + 6CO₂₍g) + 7H₂O₍l)

Use the observations provided and LeChatelier's principle to interpret the results of the following stresses placed upon the equilibrium system shown above:

  1. The system at equilibrium is placed in a filter flask and attached to a vacuum aspirator, which
    removes gas from the system. The orange/red color of the solution becomes blue.
  2. In another experiment, NaOH is added to the above system at equilibrium. The orange/red color of the solution becomes more orange.
