Procedure:- Given solution NaOH(sodium hydroxide) is made upto 100ml in a standard flask. 20ml of the NaOH solution is pipetted out into a clean conical flask. Oneor two drops of phenolphthalein indicator is added. It i titrated against the standard HCl taken in burette. At the end point the pink colour is discharged. The titration is repeted till concordant values are obtained.
