A range of production processes frequently employ acid mixtures comprised of two or three acids; for example, nitric acids, sulfuric acids and hydrochloric acids. In order to use these acids safely ...

This lab includes a demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...

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 ...

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 ...

This lab includes the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

Efficient process control and consistent plant operations are the key to success in the petroleum refinery. One of the main issues faced in the refining process is corrosion, due to which the ...

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 ...

As the Titration Product Specialist at Metrohm USA in Riverview, Florida, Eduardo Simoes, MSc, leverages 22 years of practical experience in potentiometry and electroanalysis. His expertise spans ...

Karl Fischer titration is based upon the original Bunsen reaction: which was later modified to the final equation: The reaction titrates the volume of KF reagent required to react the iodine until all ...

The KF reaction is based upon an early reaction called the Bunsen reaction, in which sulfur dioxide is oxidized by iodine with the consumption of water during this oxidation. The original reaction is ...
