how do you prepare 1M sulphuric acid from concentrated sulphuric acid?First consider the molecular weight of H2SO4 = 98 g/mol, then you have to add 98g of acid and make up to 1 liter of water....
No, although "concentrated" sulfuric acid (essentially pure H2SO4) is less dissociated than dilute sulfuric acid, simply because there's no water around for it to dissociate in.
WARNING: DO NOT DO THIS AT HOME!! Well first you get some sulphuric acid out of a car battery. Just 20ml. Then boil it for about 2 minutes. It depends on how diluted the acid is.And there you go!
