Note: This process should be carried out in a fume hood due to the release of HCl gas, which is corrosive and harmful to inhale.

1. Initial Concentration (approximately 6 M):

- Carefully add 500 mL of concentrated HCl (approximately 12 M) to a 1000 mL volumetric flask.

- Slowly add distilled water to the flask until the volume reaches 1000 mL.

- Swirl the flask gently to ensure thorough mixing.

Expected Molarity: Approximately 6 M HCl solution.

2. Dilution to Desired Concentration (e.g., 0.1 M):

- Transfer 17 mL of the prepared 6 M HCl solution into a clean 1000 mL volumetric flask using a graduated pipette.

- Add distilled water to the flask until the volume reaches 1000 mL.

- Mix thoroughly by swirling the flask.

Expected Molarity: Approximately 0.1 M HCl solution, ready for standardization.

Preparation of NaOH solution:

1. Initial Concentration (approximately 0.5 M):

- Carefully add 8 g of solid NaOH pellets to a clean 1000 mL beaker.

- Dissolve the NaOH in approximately 800 mL of distilled water, stirring continuously.

- Transfer the solution into a 1000 mL volumetric flask.

- Rinse the beaker with a small amount of distilled water and add it to the flask.

- Swirl the flask to ensure thorough mixing.

Expected Molarity: Approximately 0.5 M NaOH solution.

2. Dilution to Desired Concentration (e.g., 0.1 M):

- Transfer 200 mL of the prepared 0.5 M NaOH solution into a clean 1000 mL volumetric flask using a graduated pipette.

- Add distilled water to the flask until the volume reaches 1000 mL.

- Mix thoroughly by swirling the flask.

Expected Molarity: Approximately 0.1 M NaOH solution, ready for standardization.

It's important to note that the expected molarities mentioned above are approximate. Accurate molarity values should be determined by performing standardization processes involving titrations against a reference standard solution of known concentration.
