Description
Предлагаемый способ приготовлени индикатора дл определени концентрации водородных ионов вл етс видоизменением способа, описанного в патенте № 17831.The proposed method of preparing an indicator for determining the concentration of hydrogen ions is a modification of the method described in patent No. 17831.
Дл приготовлени индикатора берут в смеси одну объемную часть 0,1%-го раствора монокалиевой (или монолитиевой ) соли ортокарбоксибензолазодиметиланилина , половину объемной части 0,24%-го раствора монокалиевой (или монолитиевой ) соли тимолсульфонфталеина, тридцать объемных частей 0,2%-гoJCПИpтового раствора 2, 6 динитрофенола.В качестве растворител примен ют этиловый спирт, крепостью не ниже 50°. Диапазон действи индикатора от ,0 до рН 4,0. Цветовые переходы от розового цвета далее через оранжевый к желтому цвету.To prepare the indicator, take in a mixture one volume part of a 0.1% solution of monocotassium (or monolithium) salt of orthocarboxybenzene azodimethylaniline, half of the volume part of a 0.24% solution of monocotassium (or monolithium) salt of thymolsulfonphthalein, thirty volume parts of 0.2% - A solution of 2, 6 dinitrophenol. Ethyl alcohol with a strength not lower than 50 ° is used as a solvent. The range of the indicator is from 0 to pH 4.0. Color transitions from pink further through orange to yellow.
В виде -видоизменени способа приготовлени индикатора можно брать в смеси: одну объемную часть 0,1 %-го раствора метанитробензолазосалициловой кислоты,три объемных части 0,04%-го раствора монокалиевой (или монолитиевой ) соли тимолсульфонфтапеина, половину объемной части 0,01%-го раствора монокалиевой (или мо олитиевой) солиAs a variation of the method for preparing the indicator, one can take in a mixture: one volume part of a 0.1% solution of methanitrobenzene azasalicylic acid, three volume parts of a 0.04% solution of monopotassium (or monolithium) salt of thymolsulfonftapein, half of the volume part of 0.01% of the solution of monopotassium (or monolithic) salt
дибромтимолсульфонфталеина, две с половиной объемных части 0,1 %-го спиртового раствора 1,3,5 тринитробензола. Растворитель-этиловый спирт крепостью не ниже 60. Цветовые переходы от зеленого цвета через синий к коричневооранжевому цвету. Диапазон действи от рН 8,5 до рН 13,0.dibromothymolsulfonphalein, two and a half volume parts of a 0.1% alcoholic solution of 1,3,5 trinitrobenzene. Solvent-ethyl alcohol with a strength not lower than 60. Color transitions from green through blue to brown-orange color. The range of action is from pH 8.5 to pH 13.0.
Также дл индикатора можно брать смесь: двух объемных частей 0,12%-го раствора монокалиевой (или монолитиевой ) соли фенолсульфонфталеина, шести с половиной объемных частей 0,04%-го раствора монокалиевой (или монолитиевой ) соли дибромортокрезолсульфонфталеина , половины объемной части 0,04%-го раствора монокалиевой (или монолитиевой ) соли тетрабромфенолсульфонфталеина .Also for the indicator you can take a mixture: two parts by volume of a 0.12% solution of the monopotassium (or monolithium) salt of phenolsulfonphthalein, six and a half volume parts of a 0.04% solution of the monopotassium (or monolithium) salt of dibromotroresresulfonsulfonfaleine, half of the volume portion 0, 04% solution of monopotassium (or monolithium) salt of tetrabromphenolsulfonphthalein.
Растворитель-вода, водный спирт или 95%-ьш этиловый спирт.Solvent-water, aqueous alcohol or 95% ethyl alcohol.
Диапазон действи от рН 5,2 до рН 7,8. Цветовые переходы от желтого цвета через краснокоричневый к малиновокрасному .The range of action is from pH 5.2 to pH 7.8. Color transitions from yellow through red brown to crimson red.
