WebbThe two most common techniques are chemical and electrochemical etching. Chemical etching is typically a combination of either an acid or base with an oxidizing or reducing agent in a solute such as an alcohol. Electrochemical etching is a combination of chemical etching with an electrical voltage/current. Return to top WebbThe results show, in agreement with previous suggestions from this laboratory, that ethanol is firstly oxidized to acetaldehyde via a reaction initiated by nitric acid but carried on by NO 2 radical. The latter is formed by the interaction of nitric and nitrous acids. Webb1 part nitric acid .
