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 ...

Estimates show that without the usage of fertilizers, around half of the world’s population could not be supported 1. Thus, in the modern world, agriculture at significant scale without fertilizers is ...

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 ...

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 ...
