The solution that will be in the burette for the first set of titrations (standardisation of your diluted NaOH) will be e. KHP solution.

KHP, or potassium hydrogen phthalate, is a weak acid that is often used to standardise strong bases like NaOH. This is because it is a solid, allowing for accurate mass measurements, and it only has one acidic proton, simplifying the calculation of the molarity of the NaOH solution.

Here are the steps for this process:

1. Accurately weigh a sample of KHP and dissolve it in distilled water in a flask.
2. Add a few drops of phenolphthalein indicator to the flask. This will turn pink in the presence of a base.
3. Fill the burette with the diluted NaOH solution.
4. Slowly add the NaOH solution from the burette to the flask, while stirring the solution in the flask.
5. Stop adding NaOH when the pink color just disappears. This is the endpoint of the titration.
6. Record the volume of NaOH solution used. This can be used to calculate the molarity of the NaOH solution.
