Abstract : In nitric acid solutions, apart from the evolution of hydrogen at the ca ode, two electrochemical proce ses are possibl : the reduction of nitric acid to nitrous and of nitrous acid to itrou oxide The cathode reduction of nitric acid o nitrous acid proceeds on an inert platinum electrode and on passive metals and alloys if the solution contains undissociated molecules of nitric acid (greater than 18%). The cathode reduction of nitrous acid to nitric oxide is observed on a pl tinum electrode in completely dissociated solutions of nitric acid upon the addition of nitrous acid. Similar results are obtained with other etals and alloys wh n they dis olve from the active s ate provided he products of their self-solution are able on acidification to re uce solutions of nitric acid to nitrous acid.
