New computer calculations have revealed that a century-long assumption in chemistry is wrong. At the crux of the matter is the movement of the hydroxide ion, OH –, in water. Hydroxide ions and protons ...

Spectroscopic data shows that a hydroxide ion can donate a hydrogen bond to water, supporting one of two previously proposed mechanisms for its unusually fast transport in aqueous solution. The ...

A new study provides fresh insight into traditional acid-base chemistry by revealing that the mutual neutralization of isolated hydronium (H₃O⁺) and hydroxide (OH⁻) ions is driven by electron transfer ...

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 ...

Cations can be identified with flame tests or precipitate tests using sodium hydroxide and ammonia solutions. Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests or ...
