Description
Предлагаемые индикаторы дл определени концентрации водородных ионов в растворах, содержащих сахара, относ тс к индикаторам, в которых дл повышени чувствительности примен ют смесь растворов индикаторов.The proposed indicators for determining the concentration of hydrogen ions in solutions containing sugars refer to indicators in which a mixture of indicator solutions is used to increase sensitivity.
Нижеописываемые индикаторы охватывают диапазон от ,0 ,4 и предназначены специально дл работы со специфически окрашенными сахарными растворами. Применительно к тре бованию , предъ вл емому сахарной- индустрией , чувствительность- индикаторов увеличена, а именно: ошибка при употреблении их +0,2Ph.The indicators described below cover the range from, 0, 4, and are designed specifically for working with specifically colored sugar solutions. In relation to the requirements imposed by the sugar industry, the sensitivity of the indicators is increased, namely: the error in using them is + 0.2 Ph.
Дл приготовлени индикатора, с диапазоном действи от до ,2 берут смесь из одной объемной части водного раствора т-Динртрофенола с концентрацией в 0,025% и семи объемных частей водного раствора монока лиевой (или монолитиевой) соли ортокарбоксибензолазодиметиланилина с концентрацией в 0,02%. Чувствительность: ±2Ph, цветовые переходы-от красного к желтому цвету.To prepare the indicator, with a range of from to, 2, a mixture is taken from one volume part of an aqueous solution of t-Dynrtrofenol with a concentration of 0.025% and seven parts by volume of an aqueous solution of the mono-linear (or monolithium) salt of orthocarboxybenzene azodimethylaniline with a concentration of 0.02%. Sensitivity: ± 2Ph, color transitions from red to yellow.
Дл изготовлени индикатора с диапазоном действи от ,4 до ,2 примен ют смесь из трех объемных частей водного раствора монокалиевой (или монолитиевой) соли тимолсульфонфта1гина с концентрацией в 0,04%, трех объемных частей водного раствора метанитррфенола с концентрацией в 0,3% и п ти объемных частей водного раствора монокалиевой (или монолитиевой) соли фенолсульфонфталеина с концентрацией в 0,02%. Чувствительность: ±0,2Ph.For the manufacture of an indicator with a range of from 4 to 2, a mixture of three parts by volume of an aqueous solution of thymol sulfonyl fluorine-1 monopotassium (or monolithium) salt with a concentration of 0.04%, three parts by volume of an aqueous solution of methanethrphenol with a concentration of 0.3% and Five parts by volume of the aqueous solution of phenolsulfonphthalein monopotassium (or monolithium) salt with a concentration of 0.02%. Sensitivity: ± 0,2 Ph.
Цветовые переходы - от желтого к красному цвету.Color transitions are from yellow to red.
Дл диапозона действи от Ph 9.Q до Ph 12,4 индикатор составл етс из смеси одной объемной части водного раствора монокалиевой (или монолитиевой ) соли фенолсульфонфталеина с концентрацией в 0,02%, дес ти объемных частей- спиртового (96%) раствора фенолфталеина с концентрацией в 0,17% и двадцати объемных частей спиртового (96%) раствора 2-4-диоксибензолазопаранитробензола с концентрацией в 0,16%. Чувствительность: ±0,2Ph. Цветовые переходы: от красного к коричневому цвету.For the range from Ph 9.Q to Ph 12.4, the indicator is composed of a mixture of one volume part of an aqueous solution of phenolsulfonphthalein monopotassium (or monolithium) salt with a concentration of 0.02%, ten parts by volume of alcohol (96%) phenolphthalein solution with a concentration of 0.17% and twenty parts by volume of an alcohol (96%) solution of 2-4-dioxybenzene azoparanitrobenzene with a concentration of 0.16%. Sensitivity: ± 0,2 Ph. Color transitions: from red to brown.
