ratio of preparation of diluted sulphuric acid from concentrated acid?

Question

how to make 100ml dil.sulphuric acid from con.acid

Answer 1

Depends on what the molarity of the concentrated acid is and what the final concentration you want.

typical formula is: (final volume x final concentration) / initial concentration = initial volume

Answer 2

it depends on the concentration you want. One thing to remember is to add water to whatever vessel you are using and then add the acid very slowly. You should never pour water into concentrated acid. It will get very hot very fast.

Answer 3

It depends how diluted the final solution you want. If you want to prepare 1 N H2SO4 from 18N H2SO4. Its N1V1=N2V2, 18(V1)=1(100ml)=5.56 ml of 18 N H2SO4.
