Example is quinonhydrone electrode. It is prepared by the platinum strip or wire which is contained in the glass tube. The electrode is dipped in the solution with unknown pH that is needed to determine and to add some quinonhydrone\u2019s crystalls in this solution. Quinonhydrone is a crystalline product which consists of quinone (benzoquinone) \u04216\u041d4\u041e2 and hydroquinone C6H4(OH)2. It is less solubility in water and decomposes into quinone and hydroquinone in the solution. In the saturated solution equal molar mixture of quinone and hydroquinone is formed.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
