Ingredients

• Potassium Acetate (98.142g/mol)
• Glacial Acetic Acid

Equipment

• Magnetic Stirrer
• pH Meter (freshly calibrated right before use)
• Analytical Balance
• 500mL Beaker
• 250mL Volumetric Flask
• 250mL Storage Bottle

Step By Step

1. To a 500mL beaker add 200mL (150mL if you plan to use more dilute acetic acid than glacial) of distilled water and begin stirring.
2. Add 73.607g of Sodium Acetate to the water. Allow the crystals to fully dissolve.
3. Calibrate your pH meter and place the probe in the solution.
4. Adjust the pH to 5.5 using Glacial Acetic Acid. WEAR GLOVES AND SPLASHPROOF GOGGLES. f you do not have glacial acetic acid then the highest concentration of acetic acid you can find. Restaurant grade white vinegar concentrate comes in at about 10% to 30% acetic acid.
5. Carefully pour the contents into a 250mL volumetric flask and top off the flask to the 250mL neck mark with distilled water. Invert several times to mix the solution.
6. Transfer solution to a 250mL bottle with a tight screw cap, label bottle, and store at room temp.

Notes

• BE CAREFUL WITH GLACIAL ACETIC ACID AND WEAR PROPER PPE
• WORK IN A WELL VENTILATED AREA
