electrolysis of gold nitrate

Electrolytic Etching. Ethical Making Resource

It is important to note that table salt will not reliably etch silver or gold but a good result can be obtained by using sodium nitrate solution (NaNO 3). The anode can be either the same as the metal being etched or stainless steel. This holds for all metals being etched, excepting aluminium, which can only be etched using a stainless steel anode.

Electrochemical removal of nitrate ion from aqueous

Sep 05, 2005· The main problem in the process of the electrochemical removal of nitrate from aqueous solutions and wastewaters, when the electrolysis is performed at a constant potential, is the production of more toxic side-products than nitrates, such as NO 2 − and NH 3.This work deals with the removal of nitrate by square, sinusoidal and triangular wave pulsing potential electrolysis.

THE ELECTROLYSIS OF SOLUTIONS chemguide

The electrolysis of silver nitrate solution using a silver anode. This is an example of a case where you are using an electrode which gets chemically involved in the reaction. At the cathode. If you electrolyse silver nitrate solution using silver as the anode, silver is deposited on whatever material the cathode is made of as you would expect.

17.7 Electrolysis Chemistry

The metals commonly used in electroplating include cadmium, chromium, copper, gold, nickel, silver, and tin. The anode is a silver electrode. Both electrodes are immersed in a silver nitrate solution. electrochemical cells with negative cell potentials (meaning a positive Gibbs free energy), and so are nonspontaneous. Electrolysis can
