The hydrogen ion concentration of the whole blood of normal males and of cancer patients measured by means of the quinhydrone electrode 1. It provides an alternative to the commonly used glass electrode in a ph meter. Quinhydrone is slightly soluble in water, dissolving to form a mixture of two substances, quinone and hydroquinone, with the two substances present at equal concentration. Rinse the orp electrode and pat it dry with a soft tissue. The quinhydrone electrode is a type of redox electrode which used to measure the hydrogen ion concentration ph of a solution in a chemical experiment. Full text is available as a scanned copy of the original print version. Repeat as necessary until a small amount of quinhydrone remains undissolved. Electrochemical cell consists in principle of two electrodes, represented by the quinhydrone electrode is a type of redox electrode which can be used to. Engineering chemistry pdf notes ec pdf notes smartzworld.
