Sodium hydroxide is added to a cylinder of aluminum nitrate, precipitating out aluminum hydroxide. When additional base is added, the precipitate dissolves. The reactions can then be reversed with the ...

A new study has been regarded as "very important" because it offers a new framework for understanding reactions in organic chemistry. In their study, the team addressed the cooperative role of ...

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 ...

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 ...

This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

A new research, affiliated with UNIST has been featured as a 'Hot Article' on the front cover of the March issue of Chemistry: A European Journal. This study has been regarded as "very important" ...
