Ferric bromate chlorate

Hydrofluoric acid like water is an associated liquid, and even the gas, as we shall soon see, is associated. It has the power of uniting with fluorides. It also seems to be an ionizing solvent for a soln. of potassium fluoride in liquid hydrogen fluoride is an excellent conductor it also possesses marked solvent powers. According to E. C. Franklin,7 the liquid readily dissolves potassium fluoride, ehloride, and sulphate sodium fluoride, bromide, nitrate, chlorate, and bromate acetamide and urea. The solvent action is not so marked with barium fluoride, cupric chloride, and silver cyanide while calcium and lead fluorides copper sulphate and nitrate ferric chloride, mercuric oxide, and magnesium metal, are virtually insoluble in this menstruum. Glass also is not affected by the liquid if moisture be absent. The liquid scarcely acts on most of the metals or non-metals at ordinary temp., though it does act on the alkali metals at ordinary temp., much the same as does water, with the simultaneous production of flame. 

In 1935, the American Federal Bureau of Investigation pointed out that the test was not specific and had reservations about its use.118 Other evaluations of the technique proved it to be completely unreliable as an indicator of FDR. Common substances such as tobacco, tobacco ash, fertilizers, certain pharmaceuticals, certain paints, and urine also give positive results.119120 In addition a number of oxidizing agents such as chlorates, bromates, iodates, permanganates, chromates, vanadates, molybdates, antimony(V), and ferric salts also give a reaction.121,122 At the Interpol Conference in Paris in 1968 it was officially concluded that the paraffin test should no longer be used.123... 

Rao and co-workers [82] reviewed several ways of synthesising PANI using electrochemical and chemical oxidative polymerisations. Oxidising agents that have been studied include ammonium persulfate, potassium dichromate, ferric chloride, potassium permanganate, potassium bromate, potassium chlorate [83], tetrabutyl ammonium phosphate [84] and hydrogen peroxide [85]. 

This procedure revealed 0.5 y nitrate ion in the presence of 500 y of the following oxidants hydrogen peroxide, and ionic species nitrite, chlorate, bromate, ferricyanide, chromate, permanganate, vanadate, molybdate, tungstate, ferric, ceric.
