For example, a beneficial therapeutic agent may be introduced into the systemic circulation of a human body by electrotransport delivery through the skin. A widely used electrotransport process, electromigration (also called iontophoresis), involves the electrically induced transport of charged ions. ...
It seemed wrong that nitrate to NO+is a reduction : N(V) --> N(III), so how does this couple for another reduction to occur: Fe(II) --> Fe(I) ?? A small part of the nitrate is decomposed by the strong acid. Part oxidizes ferrous ions to ferric ions, forming iron (III). W...
