prepare a standard solution of oxalic acid with a concentration of 0.05mol.dm3.

a report of the investigation. give the aim, apparatus, method and results.

I wonder how much you need to prepare?

I wonder what are the safey precautions with oxalic acid? Handling precaustions? storage requiremetns? labeling requirements?
I wonder what purity you need?

My calculator wonders what is the molecular mass of the oxalic acid you are using? An exactly how do you intend on massing it?

Aim: To prepare a standard solution of oxalic acid with a concentration of 0.05 mol/dm3.

Apparatus:
- Oxalic acid (solid)
- Weighing balance
- Beaker
- Volumetric flask (100 cm3)
- Distilled water
- Measuring cylinder (10 cm3)
- Stirring rod

Method:

1. Weighing the Oxalic Acid:
- Use the weighing balance to accurately measure 0.63 g of oxalic acid (C2H2O4).
- Ensure the balance is properly calibrated and use a weighing boat or paper to prevent contamination.

2. Dissolving the Oxalic Acid:
- Transfer the measured oxalic acid to a clean and dry beaker.
- Add a small volume of distilled water to the beaker and stir using a stirring rod until the solid is completely dissolved.
- Transfer the solution to a 100 cm3 volumetric flask using a wash bottle to ensure all the solution is transferred. Rinse the beaker several times to ensure complete transfer.

3. Preparing the Standard Solution:
- Add distilled water to the volumetric flask until the solution reaches the mark on the neck of the flask. Use a dropper to add the distilled water slowly and reach the mark accurately.
- Stopper the flask and shake it gently to mix the solution thoroughly.
- The resulting solution in the volumetric flask is now a standard solution of oxalic acid with a concentration of 0.05 mol/dm3.

Results:
- Volume of oxalic acid used: 0.63 g
- Final volume of the solution in the volumetric flask: 100 cm3 (or 0.1 dm3)

Report of the Investigation:
The aim of this investigation was to prepare a standard solution of oxalic acid with a concentration of 0.05 mol/dm3. To achieve this, 0.63 g of oxalic acid was accurately weighed using a weighing balance. The oxalic acid was then dissolved in distilled water in a beaker, and the resulting solution was transferred to a 100 cm3 volumetric flask. Distilled water was added carefully to the volumetric flask to reach the mark accurately on the neck of the flask. The flask was stoppered and gently shaken to ensure thorough mixing. The resulting solution is a standard solution of oxalic acid with a concentration of 0.05 mol/dm3.
