During the titration of a particular acid, the PH changes from 7.0 to 9.0 with the addition of 0.01mL of base. An indicator was used that had KI= 1.0x10-8. Calculate the ratio of basic to acidic forms of the indicators before and after the last 0.01mL of base was added. Use the result of your calculation to explain why this would or would not be a good indicator for this titration compared to phenolpthhalein.

a. I got PH change, then need to multply by 0.01ml of base. But why? What is that number called?

b. Need to calculate ratio of basic to acidic forms of the indicator before and after the last 0.01ml of base was added. I need precise steps of calculation with explainations.

c. How can I use my calculation to explain that the indicator used is good or bad for the experiment? Pleas explain.
