Question

Write the chemical equation for the decomposition of sulfuric acid using the 9v battery? (no sulfate ion is not involved in this reaction)

Answer 1

Reduction: 2 H(+) + 2 e(-) ==> H2 oxidation: 2 H2O ==> O2 + 4 H(+) + 4 e(-) Balances as: Reduction: 4 H(+) + 4 e(-) ==> 2 H2 oxidation: 2 H2O ==> O2 + 4 H(+) + 4 e(-) Which gives : 2 H2O & 4 H(+) ==> 2 H2 & O2 + 4 H(+) Reduced answer is: 2 H2O ==> 2H2 & O2
