I'm doing a lab for Le Chatelier's Principle. I'm concerned that all my answers sound very similar. Can someone help me and let me know if my answers are making sense?

Question

~Thanks

1.) How is the reaction Zn(OH)2 <=> Zn^+2 + 2OH- affected by adding OH-

I think since we are adding a reactant the reaction favors products. So it shifts towards the left.

2.) How does an increase in H^+ effects the reaction H2) <=> (H^+) + OH^-

I think increasing the reactants favors the products. So it shifts towards the left.

3.) How does an increase in OH^- effect reaction Zn+2 + 4OH^- <=> Zn(OH)4^-2

I think increasing the reactants favors the products. So it shifts towards the right.

4.) Based on the last question #3 what does your answer from that question do to this reaction. Zn(OH)2 <=> Zn^+2 + 2OH^-

I think the effect would be the reverse because increasing the product OH^- in this equation would favor the products which would result in a shift to the left.

5.) How does an increase in (NH3) effect the reaction Zn^+2 + 4NH3 <=> Zn(NH3)4^+2

I think increasing the reactants favors the products. So it shifts towards the right.

Answer 1

a. Adding OH increase the products, so the reaaction will try to undo that and move to the left.
b. adding H+ increases the prducts, so the reacation will try to undo that and move to the left.
c. shifts to the right to undo the adding of the OH
d. shifts to left to reduce the OH added.
e. shifts to right to undo the increase in ammonia.
