Webcopper (iodometric titration) and zinc (EDTA com-plexometric titration with xylenol orange indicator) have been shown to be very effective because they provide accurate results for a wide range cyanide brass plating bath compositions. By Z. Panossian*, J.V. Ferrari & M.B. de Almeida The simplicity, quickness and relatively low cost make Weboxidation and reduction reaction as well as iodometric reaction. Titration involving with iodine or dealing with iodine liberated in chemical reaction is called Iodimetric and Iodometric titration respectively. This reaction is iodometric because iodine is got from KI. The reaction takes place in two steps: 1. Cu2++ KI + H + = I2
