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 ...

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 ...

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 ...
