Hypochlorite reduction, reaction 15, is a mass transport controlled reaction in the absence of chromate in the electrolyte and takes place easily on most electrode materials. Chlorate reduction (reaction 16), on the other hand, is kinetically controlled and chlorate is present at a high...

An Interesting final step has been reported In a procedure for the determination of fission Iodine 1n the water coolant of nuclear reactors (200). After some of the usual chemical steps oxidation of Iodide carrier to periodate by means of hypochlorite reduction of periodate to elemental Iodine with hydroxyl-amine hydrochloride and extraction of Iodine into carbon tetrachloride, the Iodine was adsorbed from the carbon tetrachloride solution onto activated carbon. The chemical yield for the procedure was 92%. 

The most common chemical bleaching procedures are hypochlorite bleach for cotton hydrogen peroxide bleach for wool and cotton sodium chlorite bleach for cotton, polyamide, polyester, and polyacrylonitrile and reductive bleaching with dithionite for wool and polyamide. 

Dicarboxylic acids have been prepared by the stepwise acylation and Wolff-Kishner reduction of thiophene or di-2-thienylmethane with ester chlorides of dicarboxylic acids. Another method consists of the AICI3 catalyzed acylation of w-phenylalkylthiophenes which occurs both in the free thiophenic position and in the para position of the ring (226). Hypochlorite oxidation and desulfurization then give diacides such as (227)... 

Redox reactions occur in the reduction of ores (metal oxides) into pure metals and the corrosion (oxidation) of pure metals in the presence of oxygen and water. Rusting iron, 4Fe + 30, + 611,0 —> 4Fe(OH), is a good example of metal oxidation. Strong oxidizing agents can be used as antiseptics (hydrogen peroxide, Fd,0,) or bleaches (sodium hypochlorite, NaOCl).

Treatment with two equivalents of tert-butyl hypochlorite and subsequent reduction with sodium/naphthalene. 

Current world chlorate production (about 700 kilotons per year) is based entirely on an electrochemical method where reactions (15.21) to (15.34) occur simultanously in undivided cells. A small amount of bichromate ions are added to the solution to reduce chlorate losses by rereduction at the cathode these form a thin protective layer at the cathode which passivates the reduction of chlorate and hypochlorite ions.
