Suppose 5.0 g of salicylic acid is heated with an excess amount of acetic acid. What is the expected yield of acetylsalicylic acid?

This reaction will not proceed, as the equilibrium is far to the left. In order to synthesize acetylsalicylic acid, one must use acetic anhydrate, and the reaction forms acetic acid instead of water.

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 are the compound names for salicylic acid and acetic anhydride?
Your question has the names right in it. Maybe it's the chemical formulas you want. In that case, salicylic acid is C7H6O3 and acetic anhydride is C4H6O3.
Why acetylsalicylic acid is not a phenol group?
ASA (acetylsalicylic acid) or Aspirin is synthesised by reacting Salicylic Acid with Acetic Anhydride. During this esterification, the dehydration occurs on the hydroxyl group attached to the benzene ring. As a result, the product no longer possesses the Phenol functional group.
What would happen if the sulfuric acid was left out in the reaction between acetic anhydride and salicylic acid to prepare acetylsalicylic acid?
Because Salicylic Acid reacts with Acetic Anhydride in the presence of H2SO4 and CH3COOH to give Aspirin. The sulphuric acid does not react. If you measure the volume/weight of the acid before the reaction and after the reaction, there will be no change. Note:-You can also use Acetyl Chloride in the presence of phosphoric acid instead on Acetic Anhydride.
What is mechanism reaction between salicylicacid and acetic anhydride?
acetic an hydride formula is (CH3CO)2O in salicylic acid for benzene ring OH and COOH are present ortho to each other. When we terate the acetic an hydride with salicylic acid, Hydrogen as a positive charge from slicylic acid (from OH not from COOH) and CH3COO as a negetive chare will replaces and finally acetyl salicylicylic acid will form,it is also called as ASpirin.acetic acid is also forms
What is the process of making aspirin?
Aspirin is made when salicylic acid and acetic anhydride is reacted in the presence of an acid catalyst such as H2SO4. Acetylsalicylic acid (aspirin) and acetic acid is formed. The reaction is an esterification reaction.
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 compound of aspirin?
The active medical ingredient in Aspirin is acetylsalicylic acid, or A.S.A.
Which from acetic acid or salicylic acid in aspirin is an alcohol?
Aspirin is a protected name belonging to Bayer A.G. (in some countries) for acetylsalicylic acid. Salicylic acid is a beta-hydroxy acid, meaning that it's both an acid and an alcohol. It serves as the alcohol in the esterification reaction.

What is the difference between old and new aspirin?
When aspirin gets old, it begins to decompose and you get a vinegar smell. If you smell that, the aspirin is decomposing and acetic acid is being released. Aspirin should be used before the decomposition occurs. It will still work, because the salicylic acid that does the work is still there. It can be corrosive to the stomach and that's why they combine it with a process that produces acetylsalicylic acid (aspirin). When decomposition occurs, you get salicylic acid and acetic acid.
What causes water to taste like aspirin?
Aspirin tastes a little bit like vinegar and the older the aspirin is, the more it tastes like vinegar. This is because vinegar is a solution of acetic acid and aspirin is made from acetic acid and salicylic acid.

Could aspirin mixed with shampoo good for treating dandruff problem?
Aspirin is also known as acetylsalicylic acid. Due to the name being so close to salicylic acid, which is commonly found in dandruff shampoos, some people figure it is the same thing. They are related, because aspirin is created through a reaction between salicylic acid and acetic acid, but they are not the same. Acetic acid is actually corrosive to skin. It is better to just stick to products that actually contain salicylic acid, like some formulas of Head and Shoulders or Selson Blue. It will tell you on the label.
What would happen if the sulfuric acid was left out in the reaction between acetic anhydride and salicylic acid to prepare acetylsalicylic acid?

Aspirin decomposition reaction equation?
Do you mean formula? Structure? Equation implies there is a reaction taking place.Aspirin's full chemical name is 2-ethanoyl hydroxybenzoic acid and the formula is C9H8O4I've already tried and failed once to render a molecular structure using text so if you want to know that it takes 10 seconds of googling.-- JT
