H2SO4 in aspirin

Answer 1

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.

Answer 2

It is an acid catalyst and a dehydrant.

It is also hygroscopic and absorbs water.

(Water is released in the synthesis of aspirin)

Answer 3

Sulfuric acid acts as a catalyst and dehydrant. It is also serves as a source of protons during the esterification of salicylic acid with acetic anhydride.

Answer 4

Sulphuric acid is used as a catalyst in the preparation of aspirin.

Answer 5

The role of sulphuric acid in the synthesis of aspirin is of a catalyst, and it is also a source of protons for carrying out the esterification of salicylic acid with acetic anhydride.

Answer 6

The usual use of sulfuric acid in organic reactions is to promote dehydration reactions.

Answer 7

It's a catalyst!

Answer 8

no
