Equilibrium - Prelab Questions

Prelab Questions



3. Consider the following equilibrium.

Mg(OH)2(s) Mg+2 + 2 OH-


The tube on the left contains Mg(OH)2(s) and water. A chemical has been added to cause the change shown in the tube on the right. Suggest a possibility for what chemical could have been added.





4. Methanol has the formula CH3OH and can be produced by the reaction of carbon monoxide with hydrogen gas.

CO + 2 H2 CH3OH + heat


In an attempt to maximize the yield of methanol (amount of methanol produced), a chemist would try to shift the equilibrium as far to the right as possible. Which of the following would accomplish this?
    a. heating the mixture
    b. adding an excess of carbon monoxide
    c. removing the methanol as it is formed
    d. adding a substance that reacts with carbon monoxide



This completes the prelab. You may begin the experiment.
