- Sodium carbonate powder (Na2CO3)

- Distilled water

- Measuring cup

- Spoon

- Glass jar or beaker

Steps:

1. Prepare the sodium carbonate powder: Measure the desired amount of sodium carbonate powder using the measuring cup or spoon.

2. Add water: Add distilled water to the glass jar or beaker. The amount of water will depend on the desired concentration of the solution. For example, for a 10% sodium carbonate solution, add enough water to make the total volume 10 times the amount of sodium carbonate powder.

3. Stir: Use the spoon to stir the mixture until the sodium carbonate powder is completely dissolved and the solution is uniform.

4. Adjust the concentration: If necessary, adjust the concentration of the solution by adding more sodium carbonate powder or more water.

5. Label the container: Label the glass jar or beaker clearly with the concentration of the sodium carbonate solution, the date it was made, and any other relevant information.

Note: Sodium carbonate is a basic compound. It is important to handle it with care and avoid contact with skin and eyes. Wear gloves and eye protection when working with sodium carbonate.
