what is the decomposition equation of H2SO4 when a 9V battery is used.

I couldn't find anything when a 9V potential was used.
The only thing I found was in a car battery with a PbO2 electrode the reaction is:
PbO2(s) + H2SO4(aq) --> PbSO4(s) + H2O(aq)
overall reaction
but this is typically around 12 V

Sulfuric acid is often used as the electrolyte in the hydrolysis of water. It does not decompose, the water goes off as O2 and H2.
H2SO4 ionizes into 2 H+ and SO4-- so the electrodes would attract the Hs as H2 gas and SO2 gas would go to the other along with O2.

i suppose there is ionization , the H+ going to cathode and SO4-- to anode. It is not an oxydation but an electrolysis
