How to write the chemistry procedure

Question

You were asked at design an experimental procedure to determine the molarity of a NaOH solution using pure solid oxalic acid dihydrate, H2C2O4 · 2H2O. You will use an aqueous solution of NaOH and an aqueous solution of oxalic acid dihydrate, H2C2O4 · 2H2O for your titration.

Question: What solution will the buret contain? Is the concentration of the solution known or unknown at the start of the titration? Does this solution contain an indicator?

My answer is, drop the liquid inside the buret little by little at this time, the volume of the liquid discharged from the difference between the scale before and after the drop can be accurately measured. The scale can be read up to 0.1 ml.

It is unknown at the start of the titration.

Yes, there is a solution containing an indicator. my answer is correct?

Answer 1

The solution with the known concentration should be in the buret. As you are using pure oxalic acid dihydrate, its aqueous solution can be prepared to a known molarity and should be in the buret (solution in the buret is known as the titrant). A known volume of the NaOH should be placed in a container like a beaker or Erlenmeyer flask. The indicator is placed in the container with the NaOH not the oxalic acid solution. The oxalic acid solution is added carefully until the indicator changes color which signals the endpoint of the titration. From the volume of titrant added, the molarity of the titrant, and the volume of NaOH used, the molarity of the NaOH solution can be calculated.
