Hello, I just have a small question, what are the molar concentrations for Acetic Anhydride and Sulfuric Acid?
@RoxiHulet23 күн бұрын
@@HasanAl-Mosuli the acetic anhydride is reagent grade, which is probably around 99%. The sulfuric acid is concentrated, which is 18 M.

Professor Smith, thank you! Can we skip the water bath and put it directly on the hot plate?
@RoxiHulet3 жыл бұрын
It depends on how much water or aqueous solvent you have in the flask. If there is only a small amount of aqueous substance in the flask, putting it directly on the hot plate may cause the reactants to heat up too fast and decompose. This is why a water bath is used for this particular synthesis. If there is a lot of aqueous solvent, the high heat capacity of water makes it safe to put the flask directly on the hot plate without worrying about decomposition of your reactants.

why doesnt aspirin dissolve completey in water like the medicine does? wouldthe acetic anhydride react with the water and form acetic acid?
@RoxiHulet2 жыл бұрын
Aspirin isn’t very soluble in water. You can only dissolve about 0.3 g aspirin in 100 mL of water. When you dissolve an aspirin tablet in water, what you observe is mostly just the binder material dissolving, not the actual aspirin molecule. And yes, acetic anhydride will form acetic acid when combined with water. I don’t use water in this reaction.
