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 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 ...

Two types of acid-base titration stand out: alkalimetry and acidimetry. Each method provides a precise means to measure ...

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 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 ...

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 ...

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 ...

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 ...
