To determine the strength of oxalic acid using NaOH, we will perform an acidimetric titration. This method involves the reaction between the acidic oxalic acid and the basic NaOH. The steps for this titration are as follows:

1. Prepare a standard solution of NaOH by accurately weighing a known amount of NaOH and dissolving it in distilled water.
2. Measure a known volume of the oxalic acid solution using a pipette and transfer it to a conical flask.
3. Add a few drops of a suitable indicator, such as phenolphthalein, to the oxalic acid solution. The indicator will change color at the endpoint of the titration.
4. Slowly add the NaOH solution from the burette to the oxalic acid solution while continuously swirling the flask.
5. The NaOH will react with the oxalic acid, resulting in a neutralization reaction. The indicator will change color, indicating that the reaction is complete.
6. Record the volume of NaOH solution added from the burette at the endpoint of the titration.
7. Repeat the titration two more times to ensure accuracy and consistency of results.
8. Calculate the average volume of NaOH solution used in the titration.
9. Use the stoichiometry of the reaction between oxalic acid and NaOH to determine the strength of the oxalic acid solution.

By following these steps, we can accurately determine the strength of oxalic acid using NaOH through acidimetric titration.
