A COLORIMETRIC REACTION OF CHLORIDE ION

A colorimetric reaction of chloride ion.

Specificity of Reactions-Several alkaloids were tested for their reaction with chloride, bromide, and iodide ions. The test system was as follows: From 0.01 to 0.05 milliequivalent of the halogen compound (sodium salt) was placed in calorimeter cuvettes. Water was added to make a volume of 5 ml. and then 2 ml. of 50 per cent phosphoric acid were added. 1 ml. of a 1 per cent solution of the alka...

A colorimetric reaction to quantify fluid mixing

We found the colorimetric reaction of Tiron (1,2-dihydroxybenzene-3,5-disulfonic acid) and molybdate suitable for optical quantification of chemical reaction during fluid–fluid mixing in laboratory chambers. This reaction consists of two colorless reagents that mix to rapidly form colored, stable, soluble products. These products can be digitally imaged and quantified using light absorbance to ...

A Colorimetric Method for Determination of Serum Chloride.

HAVE INSTITUTED a colorimetric chloride procedure which has been in use for 3 years in our laboratory and has met with great success. This colorimetric method is based on a procedure used in automated syStems* (2, 3). It is extremely simple, quite accurate, and gives highly reproducible results even in the hands of student technicians. Those laboratories not having access to a chloridometer or ...

A colorimetric reaction for the quantitative estimation of nicotinic acid.

Microestimation of citric acid; a new colorimetric reaction for pentabromoacetone.

In an earlier publication’ a method was described for the determination of citric acid in blood serum for amounts as low as 5 y. While this method permitted determinations on from 0.5 to 1.0 ml. of serum, a need was felt for a method which would be suitable for smaller amounts for children. This need was felt most acutely when samples were drawn at frequent intervals from the same child. The ex...
