an equilibrium exists between chromate ion and the dichromate ion when potassium chromate is dissolved acid. the net ionic equation describing this reaction is given in the follwering equation:

2 CrO4^2- (aq) + 2 H3O^+ (equilibrium symbol) Cr2O7^2- (aq) + 3 H2O (l)

a student studying this equilibrium begins w/ an equilibrium mixture that is light orage in color.

a. what change will the student observe when a solution of H2SO4 is added to this mixture at equilibrium?

b. briefly explain the above answer

c. what change will the student observe when a solution of NaOH is added to another example of this solution at equilibrum. why?
