DEFINITION

Classification: 205/527

Mercury or amalgam cathode:

(under subclass 526) Subject matter wherein a mercury or amalgam cathode is utilized during synthesis.

SEE OR SEARCH THIS CLASS, SUBCLASS:

529, for treating the amalgamated mercury cathode with water or other agent to generate the hydroxide when combined with the electrolytic synthesis step of producing the amalgam even though no electrolytic action is claimed for the amalgamated mercury treatment step.

423, Chemistry of Inorganic Compounds,

180, for the mere treatment of mercury amalgam which may be prepared electrolytically unless an internal or external current is impressed to facilitate the action by electrolysis.
