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 ...

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 ...

ACE OF BASE A paper-based device titrates basic solutions of NaOH. The numbers at the end of each spoke indicate the concentrations of potassium hydrogen phthalate, which neutralizes NaOH, in the ...

Titration is a convenient method for analyzing petroleum products. It can measure multiple parameters, including acid number, ...

Acidity arises from the dissociation of certain compounds in water. Acids, by definition, are substances that donate protons ...

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 ...

The answer is straightforward: phenolphthalein turns colorless in an acidic solution. When the pH of the solution is below 8.3, the indicator remains in its non-ionized form, which does not absorb ...
