Is it the same as the half equivalence point?

Draw a vertical line to the x-axis from half way up the steep, neutralisation portion of the graph. Read off the volume of reagent on the x-axis, and then halve it. This is the point of half neutralisation. It represents the volume of reagent which neutralises half of the other chemical. The usual application is with buffer solutions, and at half neutralisation, pH = pKa.

Find the two points on your graph (somewhere really close to the middle you your ph curve) during which you saw the most change in ph. Average the number on these points, and that should be the half neutralisation point of a ph curve graph.

it is usually 1/2 of the curve leading to the neutralization. so lets say that u saw end point at 20ml, the half neutralization point will be somewhere around the 10ml part of ur graph. u simply draw a line to that point from ur 10 ml point and find the concentration at that point
