We have a Hoffman apparatus in our classroom, and I was wondering how come the hydrogen all goes to the left and the oxygen all goes to the right. Shouldn't some oxygen and some hydrogen be in both tubes? ... In the apparatus, one electrode is (+) and the other is (-). When a water molecule splits into its elements,
