AP Writing Equation Question

For each of the following three reactions, write a balanced equation for the reaction in part (i) and answer the  question about the reaction in part (ii). In part (i), coefficients should be in terms of lowest whole numbers.  Assume that solutions are aqueous unless otherwise indicated. Represent substances in solutions as ions if the substances are extensively ionized. Omit formulas for any ions or molecules that are unchanged by the reaction. You may use the empty space at the bottom of the next page for scratch work, but only equations that are written in the answer boxes provided will be scored.

(a) A 0.2 M potassium hydroxide solution is titrated with a 0.1 M nitric acid solution.
            (i) Balanced equation:
 

            (ii) What would be observed if the solution was titrated well past the equivalence point using bromthymol
blue as the indicator? (Bromthymol blue is yellow in acidic solution and blue in basic solution.)
