Aspirin is made by the reaction of salicylic acid with acetic an hydride what is the theoretical yield of aspirin if 85.0 grams of salicylic acid is treated with excess acetic an hydride?
Since salicylic acid is being reacted with excess acetic anhydride, salicylic acid is the limiting reactant of the reaction. The balanced equation of the reaction of salicylic acid and acetic anhydride indicates that their is a 1:1:1:1 ratio between every reactant and product. Based on this, it can be concluded that the moles of salicylic acid, if reacted entirely, will yield an equivalent amount of moles of aspirin. To find the theoretical yield, you must know the molecular weight of aspirin and salicylic acid. First, the amount of moles of salicylic acid must be calculated by dividing the gram amount of salicylic acid, which is 85 grams, and dividing it by its molecular weight, which is 138.12 grams per mole.85.0/138.12= 0.615 moles of salicylic acidThis is the mole amount of salicylic acid as well as the theoretical mole amount of aspirin. To convert the mole amount of aspirin into grams, this figure be multiplied by the molecular weight of aspirin, which is 180.15980.615 x 180.1598 = 111 grams of aspirin (when rounded to 3 significant figures)
If 1.5g of salicylic acid is heated with an excess of acetic anhydride, what is the theoretical yield of acetylsalicyclic acid?
With 1,5 g of salicylic acid you can obtain theoretically 1,96 g aspirin (acetylsalicylic acid); but in the laboratory (or industry) I remember that the true yield of reaction is a little more than 90 %.
What percent salicylic acid in aspirin?
37.16% is the expected yield in the reaction of salicylic acid and acetic anhydride used to form aspirin.
What is the difference between actual yield and theoretical yield?
Theoretical= calculated
Is competing side reaction a reason why actual yield is less than theoretical yield?
No, competing side reaction is a reson why the actual yield is more than the theoretical yield.
This term indicates that a problem is asking how much of a product will be made by a reaction.?
theoretical yeild.
What is theoretical yield of a reaction?
The amount of product that is possible in a reaction.
What is yield of aspirin?
Yield (also called as actual yield) is the amount of a product (aspirin) obtained by an experiment in a chemical reaction in a laboratory.
What relationship s used to determine the percent yield of a chemical reaction?
The percent yield of a reaction measures the efficiency of a reaction. The relationship of the actual yield to the theoretical yield is used to determine this.
What is the theoretical yield of a reaction?
the ratio of theoretical yield over experimental yield is called percentage yield
How do you calculate income yield?
You must first calculate the theoretical yield of your product using the balanced equation. The crude yield is divided by the theoretical yield and multiplied by 100.
Dividing the actual yield by the theoretical yield and multiplying by 100 indicates reaction efficiency and is known as the?
percent yield
