@123Testing This is #35 Test 1 from the Barrons book
KMnO4 + H2SO4 -----> K2SO4 + MnSO4 + H2SO4 +H2O
(potassium permanganate +sulfuric acid -----> potassium sulfate +manganese sulfate +sulfuric acid +water)

It asked what the correct reduction half-reaction for the balanced equation was. The choices were actually really easy, since only one was a reduction equation, but I was so bewildered it just blew over my head.



On another thread

Familiarize yourself with acid and basic half reaction balancing as well, and it’ll be a breeze.

Mind posting an example too? :)
