Using starch to dispense indicators and reagents

Acta Chimica Slovenica, 2000
V članku je opsana nova eksperimentalna metoda, ki jo lahko uporabimo pri razvijanju pojmov s področja kislin in baz pri pouku kemije. Pri tej metodi uporabimo namesto vodnih raztopin, ki jih običajno uporabljamo pri eksperimentiranju s kislinami in bazami, mehki medij na osnovi moke, ki ima hkrati vlogo topila in vlogo trdnega nosilca.

Indices of oxidative stress under intranasal administration of deicing reagent solutions in rats

Hygiene and sanitation, 2021
Introduction. The use of road deicing reagents (RDR) is an effective measure to reduce winter traumatism and requires enhancement of methods for evaluation of deicers safety. The aim of investigation: to study markers of oxidative stress in rat blood samples during intranasal (i/n) administration of RDR solutions, as a model of intake under natural ...

[Effectiveness of erythrocytic diagnostic reagents in indicating Shigellae].

Zhurnal mikrobiologii, epidemiologii i immunobiologii, 1983
The possibility of the preparation of dysentery antibody diagnostic reagents on the basis of adsorbed sera is shown. Such diagnostic reagents permit to determine 200000-600000 microbial bodies or 0.0008-0.0016 microgram of the antigen per ml. The use of antigenic erythrocytic diagnostic reagents for the indication of shigellae is expedient in the ...

A Facile Method for the Titration of Organolithium Reagents using Naphtylamine or Naphtylmethylamine as Indicators

International Journal of Multidisciplinary and Current Research, 2019
A simple method for the titration of alkyllithiums with sec-butanol, using naphtylamine or naphtylmethylamine as color indicator, is reported. Both amines gave sharp-end points, easily determined by color changes from brown to yellow (naphtylamine) and from green to colorless (naphtylmethylamine).
