because sulphuric acid stops reaction
chlorene
Sulfuric acid catalyzes the preparation of esters by protonating the carbonyl group of the carboxylic acid, making it more electrophilic for nucleophilic attack by the alcohol. Other strong acids like hydrochloric acid or phosphoric acid can also be used as catalysts for the esterification reaction, but sulfuric acid is preferred due to its strong acidity and low cost.
No, sulphuric acid is used.
Zinc oxide cannot be used with sulphuric acid to prepare zinc sulphate. This is because zinc oxide is insoluble in sulphuric acid, and therefore, it would not react to form zinc sulphate.

Sulphuric acid
Sulfuric acid is used in the preparation of methyl salicylate as a catalyst to promote the esterification reaction between salicylic acid and methanol. It helps to increase the reaction rate and yield of the desired product. Additionally, sulfuric acid aids in the removal of water formed during the reaction to shift the equilibrium towards the formation of methyl salicylate.
The catalyst used for making sulphuric acid is vanadium pentoxide (V2O5). It helps to speed up the reaction between sulfur dioxide and oxygen to form sulfur trioxide, which is a crucial step in the production of sulphuric acid.
Sulphuric acid is commonly used in various industries, such as chemical manufacturing, mineral processing, and battery production. It is used in the production of fertilizers, detergents, and explosives. Additionally, sulphuric acid is used in wastewater treatment to adjust pH levels and in the oil and gas industry for the refining of petroleum.
