Answers:

The titration curve, is plotted as vol of titrant vs pH here, in this situation. From the projection value for pH 7 also we can determine endpoint.

Hi,

To determine the end point more precisely, please click on the Spectrometer in the Solution info panel.
Here you can see the absorbance values. When a color change occurs at the end point spectrometer shows the absorbance values.
