Asia Avramovic Candy Acid Lab (A.S.A) Purpose: To calculate the concentration, ph and mass of the A.S.A in aspirin. Materials Mortar and Pestle 200ml Erlenmeyer flask (x3) 200ml Beaker (x2) Burette (and burette clamp) Ring stand 8.7g of solid Acetylsalicylic Acid/A.S.A (Aspirin) 0.1M of Sodium Hydroxide (NaOH) Phenolpthalein (indicator) Stir stick 25ml Graduated cylinder Procedure Using the mortar and pestle, crush the A.S.A tablets until it’s a powder Weigh 8.7 g of A.S.A Dissolve 8.7 g of A.S.A into 50.0 ml of water Using the graduated cylinder pour 10 ml of the solution into each Erlenmeyer flask Fill burette with NaOH (0.10M) Add 3 drops of phenolphthalein into each Erlenmeyer flask Titrate the NaOH into an Erlenmeyer flask, while simultaneously stirring the solution, until the solution turns light pink (the solution must remain pink)
