Abstract
DURING an investigation at this laboratory into the depolarization of oxygen electrodes by carbon monoxide, a vibrating iridium microelectrode was required. The basis of the electrode was a steel wire and, for mechanical reasons, some form of iridium plating was necessary. The plating solution detailed below gives a dark grey coherent deposit of iridium when used under the conditions stated. The resultant deposit behaves in a manner characteristic of the metal1 and is satisfactory for electrochemical work.
