An examination of chlorpromazine hydrochloride as indicator and spectrophotometric reagent for the determination of molybdenum(V)

Analytica Chimica Acta, 1977
Abstract Chlorpromazine hydrochloride (CPA) has been tested as indicator in the titration of molybdenurn(V) with cerium(IV)sulphate at room temperature in sulphuric acid medium. It gives a sharp, reversible colour change from colourless to dark-red at the equivalence point.

Titrimetric determination of sodium dithionite with potassium hexacyanoferrate(III) as reagent and methylene blue as indicator

Fresenius' Zeitschrift für analytische Chemie, 1967
A rapid titration procedure is recommended for the estimation of Na2S2O4 in commercial sodium dithionite (sodium hydrosulphite, sodium hyposulphite) and in aqueous solutions of this compound, using potassium hexacyanoferrate(III) as reagent and methylene blue as indicator.

Rapid Test Determination of Iron(II) in Aqueous Media by Reagent Indicator Paper

Journal of Analytical Chemistry, 2004
A reagent indicator paper with immobilized zirconyl hexacyanoferrate(III) is prepared for the preconcentration and determination of 0.05–500 mg/L of iron(II) in the presence of more than 100-fold amount of iron(III). The paper is stable in the presence of up to 200 mg/L of 1,1-dimethylhydrazine.

Rapid determination of copper(I, II) ions using reagent indicator paper

Journal of Analytical Chemistry, 2009
A rapid, sensitive, and highly selective test based on the reaction of copper(I) with thio-Michler’s ketone was developed for the detection and semiquantitative determination of 0.001–2 mg/L copper in natural and potable waters using preconcentration in a portable indicator device.

Use of 9-Methylfluorene as an Indicator in the Titration of Common Group IA and Group IIA Organometallic Reagents

The Journal of Organic Chemistry, 2002
9-Methylfluorene was tested as an indicator in the titration of commonly used organometallic reagents. This indicator is readily prepared in three steps from fluorenone. In THF solution the deprotonated indicator is red and exhibits a sharp endpoint.
