Le Chatlier’s Principle Postlab Question 2.

Suppose the lab staff made a much more concentrated solution of BTB stock solution than indicated. You did your calculations with [BTB] = 2.5 x 10-4 M, but the BTB stock solution was actually prepared at 2.5 x 10-2 M. Using the correct concentration, how would it change your equilibrium constant for solution 2? 

Show any calculations if necessary. 

pH of solution = 7.33

Concentration of H3O+ = 4.68 X 10-8
