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 ...

Each chemical reaction involves an enthalpy change that leads to a change in temperature. The amount of substance converted during the reaction determines the increase (i.e. exothermic reaction) or ...

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 ...

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 ...

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 ...

THE chemical determination of ascorbic acid is based upon the high reducing capacity shown by this substance with different organic compounds. One of the best known methods based upon this property is ...

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 ...

Speaker one Neutralisation reactions take place in our everyday lives. For example, there are bacteria in your mouths that convert sugar in foods to an acid which can damage your tooth enamel. So ...

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 ...
