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 ...

Acid–base titration is more than just mixing acids and bases — it’s a precise method to uncover unknown concentrations and chemical constants like pKa. By tracking pH changes as titrant is added, ...

Students will be able to explain that if two substances cause turn a pH indicator different colors, they must be different substances. Students will be able to explain that the color that a substance ...

A crash course on the basic differences between acids and bases. A crash course on the basic differences between acids and bases, complete with a classroom-friendly experiment demonstrating the ...
