Description

Proton exchange in (NH4)3PW12O40xnH2O ammonium tungstophosphoric hydrates is investigated by means of NMR. It is determined, that at hydration high degrees (n≥7) proton, contained in NH4+ ammonium ions and water molecules, form unique system, which provides for high conductivity of corresponding hydrates. At reduction of hydration degree (n=5) proton system is divided into space-separated part, and it is accompanied by reduction of electric conductivity
