How to write the complete deprotonation steps of H2SO4?

Answer 1

pi times H2 e=mcsquared Sulfur dioxide 4  ??? 3 internets possible?

Answer 2

I think.... you're asking:

H2SO4 → H+(aq) + HSO4−(aq)

HSO4− → H+(aq) + SO42−(aq)

The transfer of the H+ (proton) of a diprotic acid like sulfuric acid is a two step process.

The first equation above has the higher Ka value as it takes more energy to remove the first proton.
