Discuss what occurs to the pH of an acid solution as when it is titrated with a base. Prepare a graph which depicts an acid with a H+ concentration of 1 x 10-1 and a pH of 1 titrated with a base of NaOH pH13. Draw the graph which depicts the acid pH changing from 1 to 7, and then showing the equivalence point reached. Discuss what is happening to the H+ concentration as the pH increases from 1-7. Discuss the use of an indicator to determine the equivalence point.
