答:四氯四碘荧光素(料)C_(20)H_4Cl_4I_4O_5又名虎红,在水中极微溶解,而其二钠盐可溶于水。要配制4:30000的虎红溶液,可将四氯四碘荧光素加氢氧化钠溶液,使其转变为四氯四碘荧光素二钠。其方法为:精密称取四氯四碘荧光素0.0957g,加入0.1N NaOH3.8ml 搅拌,微热使其完全溶解,再加蒸馏水至750ml搅匀即得。
A: Tetracycline tetraiodo-fluorescein (material) C_ (20) H_4Cl_4I_4O_5 also known as tiger red, very slightly soluble in water, and its disodium salt is soluble in water. To prepare 4: 30000 tiger red solution, tetrachloro tetraiodofluorescein sodium hydroxide solution can be added to make it into tetrachloro tetraiodo-fluorescein disodium. The method is: accurately weighed tetrachloro tetraiodofluorescein 0.0957g, adding 0.1N NaOH3.8ml stirring, slightly heated to make it completely dissolved, then add distilled water to 750ml Stir well.
