What I understand about hydrolysis is split of H₂O into H⁺ and OH^-.
I don't know the reason to use NaOH or H₂SO₄ in hydrolysis..
For an example let's take hydrolysis of Acid anhydride.
We can hydrolyze it with H₂O
(RCO)₂O+H₂O 2RCOOH]
We can also use aqueous NaOH in hydrolysis..

What I understand from the above equation is that H₂O is split and reacts to give an acid(RCOOH).and then NaOH,the base reacts with it to give a salt.So here H₂O only contribute in hydrolysis.Am I correct ?

Lets take this hydrolysis.

Does this happen in this way?

If it is so.I think that here only H₂O contributes to the hydrolysis..Am I correct ?
The above hydrolysis of amide can be also done using sulfuric acid.


Let's take this one..here it uses H₂SO₄ for hydrolysis.


From all of above I think that acids and bases are used only as catalysts..Am I correct ?

Yes. They are mere catalysts. Water is not ionized very easily, or it is not a good enough nucleophile on its own, or something like that, always.
