An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

What if you could determine challenging sample parameters quickly, accurately, all without dealing with fragile sensors or ...

Efficient process control and reliable plant operations are essential for the successful running of a petroleum refinery. One of the main causes of decreased efficiency in the refining process is ...

Precise water analysis is essential in ensuring pharmaceutical products’ performance, safety, and adherence to regulations. Karl Fischer (KF) titration is a widely used method for water content ...

I’m sure many of you reading this can remember your first acid-base titrations in chemistry class—the thrill of watching the pH indicator change color, and the fear of opening the stopper too much and ...

It has been found that, in an alkaline solution, mercurochrome (disodium-dibromo-hydroxy mercury fluorescein) exhibits fluorescence which disappears as soon as the solution reaches the neutralization ...

RECENTLY, a new colorimetric reagent was introduced for the spectrophotometric determination of magnesium 1. This reagent (LaMotte Chemical Products Co., Chestertown, Md.), ...

The Optrode, a sensor from Metrohm for titrations with optical endpoint detection, was introduced in the last issue of Metrohm Information. Application specialists at Metrohm have worked out several ...

Karl Fischer (KF) titration is a redox reaction which uses the consumption of water during the reaction to measure the amount of water in a sample. It is the reference method for water determination ...
