    NaOH is added to K2CrO4 and K2Cr2O7 separately in test tubes and a color change is noted.
    HCl is added to the same two separte solutions in fresh test tubes and a colour change is noted.
    Hcl is added to the first two mixtures
    NaOH is added two the second until a colour change is noted.

    A) What would the equations for the equilibrium be between H+ and CrO4 to produce Cr2O7 and H2O?

    B) The summation equation showing both H+ and OH- in the equilibrium reaction between K2CrO4 and K2Cr2O7 ions?
