Why is pka ph at the half equivalence point




















By drawing a vertical line from the half-equivalence volume value to the chart and then a horizontal line to the y-axis, it is possible to directly derive the acid dissociation constant.

You also make sure the concentration of the indicator is much much lower than that of the analyte so that analyte and titrant determine the pH and the indicator reports on it without skewing the result.
