Should a single acid be present in the sample solution, the titration curve will exhibit a clear S-shaped profile ... with 50 mL of deionized water prior to being titrated with a strong base – for ...

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 article explores the potentiometric determination of acid number (AN) and strong acid number (SAN) in line with ASTM D664, using the example of a motor oil sample. The acid number can be ...
