First kind electrode

WebElectrodes of the second kind also can be based on complexation reactions. For example, an electrode for EDTA is constructed by cou- pling a Hg 2+ /Hg electrode of the first kind to EDTA by taking advantage of its for- mation of a stable complex with Hg 2+. Redox Electrodes . Electrodes of the first and second kind develop a potential as the ... WebThe primary characteristic of electrodes of the first kind is that it has only one phase interface. The electrode is in contact with its ion solution. The substances involved in the …

When an analyte ion (or group of ions) concentration changes, the ideal indicator electrode responds rapidly and reproducibly. The following three types are common: 1. Metallic Indicator Electrodes . Electrodes of the First Kind; Electrodes of the Second Kind ; Electrodes of the Third Kind

WebAn electrode of the first kind is a metal that responds directly to the activity of its metal ion. An electrode of the second kind is a metal electrode whose potential depends on the activity of an anion that forms a precipitate with the electrode metal ion.
