When a good indicator has been chosen, the pH at which the solution changes color is very close to the

point of the titration.
Complete the table below:
If this "point" for a particular titration occurs at pH x, a good indicator for for the titration would be ______________.
Note: Provide only 1 indicator name (even if there are other indicators possible) and make sure the spelling is correct.
X indicator
1.5
3.5
6.1
8.9
