Answer the following questions showing all work and/or a clear and concise manner.
1. What physical observation did you use to determine a shift in Equilibrium for the 1st part of this lab. Give me one of the physical observation and the chemical formula that causes that physical observation.
2. Give me your answer to 1st part of lab when you added in _________________(look at front board).
Stress: _______________________________________________________________
How rxn tries to remove stress: _________________________________________________
Circle: Make more product or more reactant
Circle: Favoring: Forward rxn or Backward rxn
Circle: Shift Equilibrium to: Left(more reactant) or Right (more product)
Solution turned: More Light Brown or More Red or No change
Compare to lab observation: __________________________________________
3. What two stresses did you write in your lab notebook (section where you answered all the questions) when you added in the sodium hydroxide from 2nd part of lab.
4. Write down what you have for Test tube _______________________(look at front board)
Stress: _______________________________________________________________
How rxn tries to remove stress: _________________________________________________
Circle: Make more product or more reactant
Circle: Favoring: Forward rxn or Backward rxn
Circle: Shift Equilibrium to: Left(more reactant) or Right (more product)
Solution turned: More Light Brown or More Red or No change OR More Yellow or More Orange or No change
