Why sulphuric acid is used for acetylation?

Could you please be a bit more specific, because usually it is not, depending on the product being acetylized. My best guess would be that it is being used as a catalyst for the reaction, in which case 'concentrated' Sulphuric acid would be used (very carefully). There are a number of other catalysts that could be used, again depending on the product in queston.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
