Transcribed Image Text:Experiment #1 – Preparation of Ascorbic Acid Stock Solution and Dilution
Materials:
500 mg ascorbic acid tablets
2L Distilled water
Measuring cups / measuring spoon
Mortar and pestle
Stirrer
Parchment paper or any non-porous sheet
Dropper or syringe with no needle (optional)
Weighing scale (optional)
Amber bottle; or Glass bottle with tint; or Glass bottle and aluminum foil
Masking tape; or Sticker label
Permanent marker
Methods:
1. On a clean, dry, and flat surface, place a parchment paper, or any non-porous flat
sheet.
2. Pulverize the required amount of 500 mg ascorbic acid tablet/(s) into fine powder.
Note: Assume that the tablet contains pure 500 mg ascorbic acid without any
excipient/(s). The amount of tablets will depend on the concentration assigned to
your group.
3. On a clean and dry glass bottle or tinted jar, add the necessary amount of distilled
water to make the desired concentration of stock solution assigned to your group.
Make sure to place the computations used in the data sheet.
