Summary
[edit]
| Description |
Русский: Происходит титрование.Титрование — процесс определения титра исследуемого вещества, метод количественного анализа в аналитической и фармацевтической химии.
Титрование производят из бюреток, заполненных рабочим раствором до нулевой отметки. Титровать, начиная от других отметок, не рекомендуется, так как шкала бюретки может быть неравномерной. Заполнение бюреток рабочим раствором производят через воронку или с помощью специальных приспособлений, если бюретка полуавтоматическая. Различают прямое, обратное титрование и титрование заместителя. При прямом титровании к раствору определяемого вещества добавляют небольшими порциям раствор титранта (рабочий раствор). Точку эквивалентности определяют индикаторами или физико-химическими методами. По количеству пошедшего на титрование рабочего раствора рассчитывают результаты анализа.English: Titration — process of determining the titer of a test substance, a method of quantitative analysis in analytical and pharmaceutical chemistry. Produced from the titration burette filled with the working fluid to the zero mark. Titrate, starting from other notes, is not recommended, as the scale of the burette may be uneven. Filling burettes produce a working solution through a funnel or with the help of special devices if the semi-automatic burette. Distinguish between direct, back titration and the pit Deputy. In a direct titration to a solution of the analyte are added to portions of the titrant solution (the working solution). The equivalence point is determined by indicators or physicochemical methods. The number went for titration of the working solution is calculated the results of the analysis. |
