Hcl cl- is a strong nucleophile capible of substituting the oH group of the salicyclic acid,, my best guess

What is the purpose of phosphoric acid in the synthesis of aspirin?
to serve as a catalyst and speed up the reaction
H2SO4 in aspirin?
Yes. ^ Well to improve on this, in simple terms. A catalyst is something that brings on the reaction, in this case the liquid catalyst can only contain a little amount of water otherwise side reactions will occur and this would impact (reduce) the yield of aspirin - not good, sulfuric acid is usually used because it is 98% pure, phosphoric acid can also be used but it is only about 85% pure, still OK. HCL in its most concentrated form is only 37% pure and there fore no good at all. In a shorter to the point answer, H2SO4 is a pure catalyst which will give you a close to accurate yield of aspirin.
Is copper sulphate the best catalyst between zinc and hydrochloric acid?
Is aqueous copper (2)sulphate an effective catalyst in the reaction between zinc and hydrochloric acid.
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.
Is aspirin the most common acid?
No. Possibly the most common simple acid would be the hydrochloric acid in your stomach.
What is an alternative reagent to ethanoic anhydride in the synthesis of aspirin from salicylic acid?
Synthesis of acetyl chloride via the reaction of acetic acid with sulphuric acid
Is stomach acid an enzyme?
Stomach acid, or hydrochloric acid (HCl), is not an enzyme, because stomach acid is neither a protein nor a catalyst.
Is aspirin synthesis an esterification reaction?
no, it is the combining of 2 acids into a new acid.
What chemicals are needed to produce aspirin?
Salycylic acid and acetic anhydride with a sulphuric acid catalyst
How will you convert phenol into aspirin?
Aspirin (acetyl salycilic acid) is prepared from salycilic acid and acetic anhydride; salicylic acid is prepared from sodium phenoxide and carbon dioxide (Kolbe synthesis).
Why do you use sulfuric acid in the preparation of banana oil experiment?
Sulfuric acid functions as a catalyst in the synthesis of banana oil.
Why maintain the temperature of the reaction at 90 degrees C in synthesis of aspirin?
To prevetn evaporation of salicylic acid
