Javelle sche Lauge. Javelle water, jawohl, adv. yes indeed. 

Antoine-Jerome Balard, 1802-1876. French chemist and pharmacist who discovered bromine. Professor of chemistry at the Sorbonne and at the College de France. He discovered hypochlorous acid, worked out the con-situation of Javelle water, and perfected industrial methods for extracting various salts from sea water. 

In 1842 Balard succeeded Thenard at the Sorbonne, and in 1851 he accepted a professorship at the College de France (36). He discovered hypochlorous acid, worked out the constitution of Javelle water (44), and perfected industrial methods for the extraction of various salts from sea water. He worked for twenty years at these technical researches, and extracted sodium sulfate, the basis of the soda industry, directly from sea water. He also extracted potassium salts from the sea water, and his artificial potash, entering into competition with that from the ashes of plants, soon lowered the price. Before the discovery of the Stassfurt deposits in 1858, all the bromine used by photographers was prepared by Balard s method. 

The resulting aqueous solution containing sodium chloride and sodium hypochlorite is known as Javelle water and is used as an antiseptic (Dakin s solution). Treatment of Javelle water with a strong acid results in liberation (in solution) of the weak and unstable hypochlorous acid... 

This mixture is known as Ldbarraque Water. The corresponding product obtained from potash is Javel Water." With lime, however, there results a compound to which the following formula is generally given ...

Bleaching powder, which in the solid state is a mixed salt (calcium chloride-hypochlorite), is commonly used for bleaching. A solution containing sodium hypochlorite, sometimes called Javelle water, is often more convenient and can be prepared by treating bleaching powder with sodium carbonate and filtering. 

Sodium hypochlorite is used almost exclusively for one of two purposes bleaching or purification. The compound is available commercially for household use under a number of trade names, including Antiformin , B-K Liquid , Clorox , Dakin s Solution , Dazzle , Hychlorite , Javelle water, Piochlor , Purex , and Saniton Toothbrush Sanitizer . About two-thirds of the sodium hypochlorite made in the United States is used as a laundry bleach and sanitizer, in restaurants and institutional kitchens for bleaching and sanitation, and for water purification in residential pools and spas. Some examples of the ways in which sodium hypochlorite is used include ... 

The bums produced by yellow phosphorus arc more serious than a like destruction of cutaneous surface by other substances. A burning fragment of P adheres tenaciously to the skin, into which it burrows. One of the products of the combustion is metaphosphoric acid (q. v.) which, being absorbed, gives rise to true poisoning. Burns by P should be washed immediately with dilute javelle water, liq. sod ohlorinat , or solution of chlorid of lime. Yellow P should never be allowed to come in contact with the skin, except it be under cold water. 

Potassium Hypochlorite—KCIO—90.5—is formed in solution by imperfect saturation of a cooled solution of KHO with hypo-chlorous acid. An impure solution is used in bleaching Javelle water. 

A common bleaching agent used domestically (more particularly in Mediterranean countries and North America) is Javel water, which is sodium hypochlorite in water. 

The Pourbaix diagrams are also used in electrochemistry to determine the curve depicting the change in open-circuit potential of an inert electrode (for example a platinum electrode) immersed in a dearated solution of Javel water when sulphuric acid is gradually added to this solution. 

To give an idea of values, let us take a Javel water solution with an initial concentration of 0.5 mol f in 00 and Cl ions, at pH=10. One can assume that it does not react with water, since the kinetics involved is extremely slow. 

Antiseptics (substances that can kill bacteria) used in minor medicine include solutions of sodium hypochlorite (Dakin s solution, Javelle water). Why is this substance effective ... 

Bleaching solutions are aqueous sodium hypochlorite. One example is Javel water in France. It can be prepared by reacting chlorine with a solution of sodium... 

Hence, Javel water may be considered a mixture of equal quantities of sodium hypochlorite and sodium chloride. Concentrated and more diluted solutions are commercially available. The latter are called ordinary Javel waters. For pharmaceutical use, there is Dakin solution, which is a diluted Javel water to which has been added some sodium hydrogen carbonate to weaken the alkaline character of the solution, which is irritating for tissues. 

In the past, Javel water was a solution of potassium hypochlorite.
