Titration of NaOH with standard 0.1 N oxalic acid solution

TITRATION

• Pipette out 5 ml of standard Oxalic acid solution into a conical flask.
• Add two drops of Phenolphthalein indicator and mix well (it will be colorless).
• Fill the burette with NaOH solution and note the initial reading.
• Then add the NaOH solution drop by drop from burette to the conical flask until a pale permanent pink color appears and note the final reading.
• Repeat the process for concordant value.
