Concept Introduction:
Autoionization of water is the reaction in which the water undergoes ionization to give a proton and a hydroxide ion. Water is a very weak electrolyte and hence it does not completely dissociate into the ions. The ionization happens to a very less extent only. The ionization of water is an equilibrium reaction and hence this has equilibrium rate constant.

You dilute 20 mL of the solution with water to a total volume of 200 mL and measure the pH again, this time it reads 3.50. You take some volume of the solution, add phenolphthalein, and titrate it with NaOH solution until the mixture turns pink. You record the volume of the required titrant as Vt and the pH meter reads 9.05. In a separate flask, you take the same volume of the unknown solution as in step iii and titrate it with the same NaOH…arrow_forward
