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 ...

Selective extraction of specific, charge-dense anions from a solution is beneficial, but has been limited in practice by the inability of anion extraction to overcome the Hofmeister bias. In ...

Silica dissolves in water to a small extent and below pH7 exists in solution essentially in a non-polar form. In this respect it contrasts with nutrient cations and anions and a study of its uptake by ...

Anion exchange membrane fuel cells (AEMFCs) have gained attention in the process of fuel cell development because they operate in alkaline environments, the redox reaction rate at the electrodes is ...
