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 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 ...

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 ...

It is thought that without the use of fertilizers, around half of the world’s population could not be supported 1. In the modern world, agriculture at a significant scale without fertilizers is no ...

To define "steady-state" chronic hypercapnia in man, we studied 20 patients with stable carbon dioxide tensions from 34 to 103 mm of mercury and with no apparent complicating disorders. The whole-body ...

THE structure of polyadenylic acid can be expected to have some influence on the availability of polar groups, such as the primary amino-group of the adenine base, for binding of hydrogen ions.

The process of carrying out a titration allows us to accurately measure the volumes of an acid and an alkali required for neutralisation. An indicator will be used to determine the exact volume ...
