A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

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 ...

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 ...

This presentation will focus on revising some of the key topics in A-Level acid-base chemistry, e.g. definitions, calculating pH, acid-base titrations, titration curves and buffer solutions as ...

The titration curves of three synthetic auxins-3-indole acetic, 3-indole propionic and 3-indole butyric acids-were determined for distilled water solutions of varying concentrations. Within the limits ...

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 ...
