Which Catalyst used in manufacture of sulphuric acid?
vanadium pentaoxide
What is the catalyst used for making sulphuric acid?
Vanadium pentaoxide
What iS the importance of Sulfuric acid in the preparation of methyl Salicylate?
Sulphuric acid used in this experiment was used only as a catalyst. So, it is not consumed.
Why is a catalyst needed in the manufacture of sulphuric acid?
The catalyst is vanadium(V) oxide (vanadium pentoxide, V2O5)
How does sulfuric acid catalyze the preparation of esters Could some other acid be used?
The concentrated sulphuric acid solution is the preferred catalyst for the preparation of esters. Rarely used is the hydrochloric acid as a gas.

What is role of sulphuric acid in dehydration of ethanol?
Acts as the dehydrating agent (catalyst).
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
Is sulphuric acid a positive catalyst?
Yes, it sometimes can catalyze esterification and nitration reactions
What chemicals are needed to produce aspirin?
Salycylic acid and acetic anhydride with a sulphuric acid catalyst
Why is sulphuric acid not used in preparation of carbondioxidei?
because sulphuric acid stops reaction
What chemicals are used in the extraction of copper?
A strong acid such as sulphuric acid is used.
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.
