# Is electrolysis of molten silver nitrate possible? [duplicate]

Since the salt is molten, the only ions are $$\ce{Ag+}$$ and $$\ce{NO3-}$$, and both of them can only do a reduction reaction. Who goes to the anode? Also, there is no acid in the solution — only the salt — therefore the following reaction cannot occur, right?

$$\ce{ NO3- + 4H+ + 3e- -> NO + H2O}$$

So, what happens? The only possible reaction is the reduction of the $$\ce{Ag+}$$ to $$\ce{Ag (s)}$$. There is literally nothing else.

• You can't have reduction without oxidation. Then again, who said they can only do a reduction reaction? – Ivan Neretin Feb 7 '19 at 9:22
• Why oxygen shouldn't evolve? – Alchimista Feb 7 '19 at 9:58
• @IvanNeretin the nitrogen and the silver already have their highest oxidation numbers. – angelo Feb 7 '19 at 10:49
• True, but are they the only elements here? – Ivan Neretin Feb 7 '19 at 11:00
• Well, if it were spontaneous, then AgNO3 would not exist in the first place, would it? – Ivan Neretin Feb 7 '19 at 12:50
