Step 2: Calculate the mass of NaOH required.
- The formula to calculate the mass of NaOH required is:
```
Mass of NaOH (g) = Molarity of NaOH solution (M) x Molar mass of NaOH (g/mol) x Volume of NaOH solution (L)
```
- For a 0.1N NaOH solution, the molarity is 0.1N, which is equivalent to 0.1M.
- The molar mass of NaOH is approximately 40g/mol.
- The volume of the NaOH solution you want to prepare is 1L.
- Plugging these values into the formula, we get:
```
Mass of NaOH (g) = 0.1 M x 40g/mol x 1L
Mass of NaOH (g) = 4g
```
Step 3: Dissolve NaOH in water.
- In a fume hood, slowly add 4g of NaOH pellets to approximately 500mL of DI water in a beaker.
- Stir the solution until the NaOH pellets have completely dissolved.
- Be cautious as the dissolution process can be exothermic and release heat.
Step 4: Transfer the solution to a volumetric flask.
- Using a glass funnel, carefully transfer the NaOH solution from the beaker to the 1000mL volumetric flask.
- Rinse the beaker with a small amount of DI water and add it to the volumetric flask.
Step 5: Fill the volumetric flask to the calibration mark.
- Add DI water to the flask until the bottom of the meniscus touches the calibration mark on the neck of the flask.
Step 6: Mix the solution thoroughly.
- Gently swirl the volumetric flask to mix the solution uniformly.
Congratulations! You have successfully prepared a 0.1N NaOH solution. Remember to label the solution appropriately with its concentration, date, and any necessary safety information. Always handle NaOH solutions with caution, avoiding skin contact and inhalation, and adhering to lab safety guidelines.
