Alternating current coulometry technique with determination of total quantity of electricity by coulometric constant. Determination of benzoquinone and hydroquinone

Method of electrochemical measurements, a direct alternating-current coulometry, based on the principles of determination the coulometric constant of the electrochemical cell is proposed. This method significantly reduces analysis time compared to the previously known analogs. The possibility of determining the quinone and hydroquinone in aqueous solutions is shown. The values of coulometric constants of electrochemical cells for the different volumes of solution were found.
