The salt which responds to dilute and concentrated H2SO4 is
CaF2
Ba(NO3)2
Na2SO4
Na3PO4
Ba(NO3)2+H2SO4(dill)→BaSO4(S)+2H+2NO3−(aq)
Suppose, in your lab, you have run out of dilute Sulphuric acid. You require dilute H2SO4 for an important synthesis but only have concentrated Sulphuric acid, water and a glass beaker. How will you synthesize dilute H2SO4 ?
Why is water not added to concentrated H2SO4 in order to dilute it ?
