the action of silver araenate upon ethyl iodide. It boils at 235° with
slight decomposition, and in contact with water it is resolved into
ethyl alcohol and arsenic acid.
Ethyl Arsenite C2H6 V AsO8 is prepared from ethyl iodide and silver
arsenite. It is a colourless liquid, boding at 166°: water decomposes
it into alcohol and arsenic trioxide.
