Detection of a sodium chlorate, reagent preparation 1) 20% sulfuric acid: amount of 890ml of deionized water to 1000ml beaker, 110ml of sulfuric acid was slowly added (96-98%), while adding while stirring, cooled standby. 2) 0.1mol / L ammonium ferrous sulfate solution: Weigh 39.15g ferrous ammonium sulfate, into 500ml beaker, dissolved plus 300ml20% sulfuric acid sodium chlorate production, coupled with deionized water, and to 1000ml . 3) Operators parathion mixed preparation: 67ml85% phosphoric acid slowly into deionized water containing 600ml beaker chlorate factory, then slowly add 267ml 96-98% of concentrated sulfuric acid, sodium chlorate, stirring constantly until cool After diluted with deionized water to 1000ml mix. 4) 10g / L with sodium: Weigh 1g diphenylamine sodium beaker add 50ml of deionized water to dissolve, to be completely dissolved, the flask volume to 100ml. Second, the experimental process in a dry Erlenmeyer flask in 10ml water weighing chlorite protection, take 2-3 drops of sample weighed sample mass of m, then was transferred to quasi-ferrous ammonium sulfate solution 25.00ml, added 75ml parathion mixture was heated on a hot plate for 3-5 minutes (bubbling bottom stop heating), cooled to room temperature with tap water, rinsed with pure water bottle, after adding 8 drops of diphenylamine sulfonate indicator, 0.1N potassium dichromate standard droplet to the solution from green to purple, 30S does not fade is the end. Record the titration volume V. At the same time a blank test, that does not add other samples are the same experiment. Blank consumed titrant volume is V0. What is the specific role of sodium chlorate role and use printing industry as a fabric dye Sunrex oxidant, but also for mordant. Inorganic industry as an oxidant, can also be used in the manufacture of sodium chlorite and perchlorate. The pharmaceutical industry for the manufacture of pharmaceutical zinc oxide, disulfide butyrate, sodium. Pigments industry for the manufacture of advanced zinc oxide and Westlands. In agriculture as herbicides. In addition, for paper making, tanning ore processing, bromine from seawater and the manufacture of printing inks, explosives and so on.
