Synthesis of aspirin lab when 5 grams of salicylic acid is used:

how much of ACETIC acid in mL should be used ( I KNOW ACETIC ANHYDRIDE IS BETTER BUT I AM ASKING FOR ACETIC ACID)?

how many drops of Phosphoric acid should be used?

How long should the mixture be heated?

What tempture should it be heated at?

How much DI water should be added (one mL at a time)?

4- Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4) and acetic acid (HC2H3O2). The balanced equation is:             C4H6O3   +   C7H6O3     →     C9H8O4   +   HC2H3O2             In a laboratory synthesis, a student begins with 3.00 mL of acetic anhydride (density = 1.08 g/mL) and 1.25 g salicylic acid. Once the reaction is complete, the student collects 1.22 grams of aspirin.Determine the limiting reactant, theoretical yield of aspirin, and...

In lab, aspirin was made from salicylic acid through a process of heating water to 85 degrees celcius, recrylstalize doing a vacuum filtrtion apparatus with both cooled and warm filtration. After heating in an oven for one hour and letting cool. The mass signficatnly decreased after heating to be about .0129 grams aspirin- the starting SA was 1.4460 why was there such a decrease? The melting point was tested using a melting point capillary with a Mel-Temp apparatus. The melting...

Organic lab. Experiment: Acetylsalicy acid (aspirin) I had 3 tubes with with 1g of salicylic acid and 2 mL of acetic anhydride. I added to tube 1 0.2g of anhydrous sodium. To tube 2 I added 5 drops of pyridine. To tube 3 I added 5 drops of concentrated sulfuric acid. I put all of them in a hot water bath. In tube 1 and 2 salicylic acid dissolved. Why 3 did not dissolve?

a)Determine the limiting reagent in aspirin synthesis given 3g of salicylic acid. b)Based on your answer, calculate the maximum weight of aspirin that you could prepare. c)As is true for most "organic" reactions the synthesis you do here is an equilibrium reaction. What steps could you take to improve the yield. d)The solubility of aspirin in ethanol is approximately 40g/100 mL at room temperature. If you had a 100% yield, how many milliliters of ethanol would you need to dissolve...
