What is the purpose of phosphoric acid in the synthesis of aspirin?
Phosphoric acid is used in the synthesis of aspirin as a catalyst to facilitate the esterification reaction between salicylic acid and acetic anhydride. It helps increase the reaction rate and yield of aspirin.
Why pyridine is used im the synthesis of aspIrin?
Pyridine is used in the synthesis of aspirin as a catalyst to help facilitate the esterification reaction between salicylic acid and acetic anhydride. Its basic properties help neutralize the acidic byproducts formed during the reaction, which improves the yield of aspirin. Additionally, pyridine can also help dissolve the reactants and promote the formation of the desired product.
What is the compound of aspirin?
The active medical ingredient in Aspirin is acetylsalicylic acid, or A.S.A.
What does it show if an aspirin solution has turned a universal indicator orange-red?
The aspirin solution is acidic; aspirin is the acetylsalicylic acid.
Solution of water and aspirin an acid?
Yes it will be weakly acidic. Aspirin's scientific name is acetylsalicylic acid, with a pKa of 3.5. This would mean that for a solution of 0.1 M aspirin, the pH of the solution would be approximately 2.26.
What factors affect the melting point of aspirin?
losing yield
Why does cold water make aspirin crystallize?
Aspirin dissolves in warm water. If cold water is used, that will give a maximum yield.
How do you improve the yield of synthesized aspirin?
I'm not sure, but when we did a lab about it we discovered that using more water to rinse the solution causes very much Aspirin to be lost in the purification process.
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 purpose of phosphoric acid in the synthesis of aspirin?
Phosphoric acid is used in the synthesis of aspirin as a catalyst to facilitate the esterification reaction between salicylic acid and acetic anhydride. It helps increase the reaction rate and yield of aspirin.
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)
Why pyridine is used im the synthesis of aspIrin?

Who found a cure for aspirin?
Aspirin is not a disease, it is a medicine. Hence, aspirin does not require a cure.
Is low dose aspirin the same as baby aspirin?
81mg is the common dosage for "baby" aspirin
Is aspirin acidic basic or neutral?
aspirin is an acid... aspirins chemical name is acetylsalicylic acid
