Calulations and observations to determine the molarity of given sodium hydroxide solution provided with M/20 oxalic acid solution

Answer 1

I think I would measure a precise volume of the oxalic solution of known molarity.
Then, titrate it with the NaOH solution, measuring the pH (or using an indicator in the acid). Keep Note the final volume, subtract the initial volume of the acid, and then, you know the volume of the NaOH, and using your titration equation, calculate Molarity of NaOH solution
