you are given dil.HCL and NaOH sol.describe an activity by which you can observe the point at which neutralisation reaction takes place completely?

Take the solutions of HCl and NaOH of approximately equal concentration say 0.25 M. Take 10 ml solution of NaOH in the beaker and fill up a burette with the HCl solution. Now add 2-3 drops of Phenolphthalein indicator in NaOH solution, now start the titration. Initially on adding the indicator color of the solution is pink and as we add HCl solution it turns pale in color and at point when just after adding one drop of HCl the pink color disappears completely, that point is called neutralization or end point.
