Chemical equilibrium

  • Thread starter lliu11
  • Start date
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?
