Using Silica Gel Beads to Dispense Indicators and Reagents

Journal of Chemical Education, 1995
Silica gel beads which have adsorbed certain chemical reagents such as acid-base indicators, detecting reagents, color-producing metal ions, and organic dyestuffs can be used in classrooms and field studies either as teaching aids or for students' laboratory work.

Examination of metallochromic indicators and water-soluble reagents for metals by planar electrophoresis

Analyst, The, 1986
Water-soluble azo, phthalein, sulphonphthalein and anthraquinone indicators and reagents were subjected to low-voltage electrophoresis on cellulose acetate sheets at pH 2–12. All dyes except low-sulphonated azo dyes yielded one or more sharp bands showing good mobility and resolution over some range of pH values.

Sensitized schiff's reagent as an acid-base indicator

Analytica Chimica Acta, 1954
Abstract The sensitized Schiff's reagent has been used as an indicator in the neutralization of strong acids by means of strong or weak bases. (1) Since the acid to alkali transition is much sharper than the reverse process, the titration is best done by adding alkali to the acid.

pH Indicators As Chemical Reagents for the Enhancement of Footwear Marks

Journal of Forensic Sciences, 1996
Abstract Enhancement of weak two-dimensional shoemarks is often necessary due to the poor image detail. Thiocyanate is regarded in the literature as the most effective reagent for the chemical enhancement of footwear marks. In this study we have examined the possibility of using pH indicators, Bromophenol Blue and Bromocresol Green, as ...

Ion-Selective Optode Nanospheres as Heterogeneous Indicator Reagents in Complexometric Titrations

Analytical Chemistry, 2015
Traditionally, optical titrations of inorganic ions are based on a rapid and visible color change at the end point with water-soluble organic dyes as indicators. Adequate selectivity is required for both the indicator and the complexing agent, which is often limited.
