Part 1 of this article was published in Chem 13 News in November 2014. This second part presents three titration exercises of increasing sophistication, suitable for students with some titration ...

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 ...

A titration experiment can be carried out to accurately measure the volume of substances that react in chemical reactions. This technique is commonly used in neutralisation reactions and can also be ...

This article introduces a novel approach for measuring the concentration of acids and bases using refractometry: an alternative to traditional titration methods. This technique offers significant ...

When titrated by a strong base such as 0.1 M NaOH solution, a solution of citric acid traverses a buffer region during which the pH of the solution climbs gradually then more steeply. From about one ...
