Because the esterification process is reversible, and we need the reaction to be one-way, the addition of sulphuric acid as a dehydrating agent stops the water from reacting with the ester to form back into an acid and alcohol. The sulphuric acid also acts as a catalyst for the reaction by protonating the carbonyl group oxygen, thus making the carbonyl group more electrophilic
Acids protonate the carbonyl oxygen, making the carbonyl group more electrophilic. Since the reaction is equilibrium limited, water is avoided, which is why conc sulfuric is typically used rather than conc HCl. p-toluenesulfonic acid (pTsOH) is also used frequently.
The sulphuric acid acts as a catalyst and provides water for the 'hydrolysis' reaction.

Sulfuric acid acts as a catalyst in esterification.
It is an acid. It produces hydrogen ions which protonate the organic acid molecule and make it easier for the alcolhol to attack it.
Sulfuric acid is a strong dehydrating agent.

works as a catalyst to speed up reaction
The product of 1-propanol and acetic acid is the compound propyl acetate. This compound is formed through the esterification process, which is a reaction of a carboxylic acid with an alcohol in the presence of a substance like sulfuric acid.
it is for it to act like an catylast meaning to speed up the procces without being consumend in the process
Yes - but it is not very efficient - concentrated is much better. Dont forget that by adding dilute sulfuric acid you are adding water which is produced by the esterification reaction. Although a catalyst does not affect the position of equilibrium, adding a product does (and water is a product) - and so it is not ideal at all as the position of equilibrium is shifted back to starting materials by Le Chetalier's Principle.
Yes,they can undergo a neutralization reaction, the reaction between sulfuric acid and ammonia is feasible.

esterification is the formation of esters between the reaction of alkanol and alkanoic acid
The product of 1-propanol and acetic acid is the compound propyl acetate. This compound is formed through the esterification process, which is a reaction of a carboxylic acid with an alcohol in the presence of a substance like sulfuric acid.
An acid catalyst is used can be in many forms such as sulfuric acid or ion-exchange resin.
Esterification Reaction: When an alcohol ( mostly primary) alcohol is treated with carboxylic acid in the presence of H2 SO4 sweet smelling compound is formed which is called ester. The reaction is know as esterification reaction.

saponification is considered to be the reverse process of an esterification reaction due to the fact that esterification is combining an alcohol and a carboxylic acid but a saponification is breaking apart the ester by adding an NaCl molecule (soap) to the chain of carbons.
no, it is the combining of 2 acids into a new acid.
To remove the sulphuric acid (H2SO4) and carboxylic acid (RCOOH).
Yes,they can undergo a neutralization reaction, the reaction between sulfuric acid and ammonia is feasible.
I think it's because sulfate is the salt of sulfuric acid. They both have the same ions, therefore have no reaction. Its like adding sulfuric acid to sulfuric acid.
