Write following electron transfer half equations: 1) Barium reacts with dilute nitric acid 2) Lithium reacts with dilute sulfuric acid?
Both of these are redox reactions. Which species are oxidized, and which species are reduced? Can you write equivalent reactions for lithium metal and nitric acid, and barium metal and sulfuric acid? Note that
Of course the half equations are:
The corresponding reduction equation is:
Are charge and mass balanced in each instance?
