Acetate (often mistakenly called acetone), can be produced from vinegar using several ingredients in a laboratory setting. Acetate is a derivative of acetic acid (a component of vinegar) and is one of the most common building blocks for biosynthesis. Applications for acetate include the formation of aluminum acetate (used in dying), ammonium acetate (a precursor to acetamide), potassium acetate (used as a diuretic), and vinyl acetate (a precursor to polyvinyl acetate). Acetate is commercially important for the production of these compounds.

Things you need
- 4 grams of sodium bicarbonate
- 500 millilitre flask
- Watch glass
- 150 millilitres of acetic acid
- 25 millilitres of distilled water
- 50 millilitre beaker
- Stirring rod
Place 4 grams of sodium bicarbonate in a 50 millilitre beaker. Pour 25 millilitres of distilled water into the beaker with the sodium bicarbonate and stir with the stirring rod until all sodium bicarbonate is dissolved.
Pour the water and sodium bicarbonate mixture into a 500milliliter flask.
Slowly pour 150 millilitres of acetic acid into the 500 millilitre flask. Wait for any bubbling to cease. Once all bubbling has stopped, stir the mixture with the stirring rod for 2 minutes and set the mixture aside.
Plug in a hotplate and place it on a secure, heatproof surface. Set the 500 millilitre flask containing the acetic acid, sodium bicarbonate and water on the hotplate and allow the mixture to reach a gentle boil. When the mixture begins to boil, cover the opening of the flask with the watch glass.
Continue to heat the mixture until all of the liquid has boiled off and only powder remains at the bottom of the flask.
Turn off the hotplate and unplug it. Allow the flask to cool to room temperature before handling it. The powder in the flask is your newly produced acetate.
