dunno if youv worked it out yet but its just a simple equilibrium question i think. If its in a solution with ph 10 there will be an abundance of OH ions.These will combine with the H+ ions in the products and will so shift the equilibrium to the right making the solution yellow as the reverse reaction cannot take place.
