Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...

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 ...

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 ...

Metal-ion hybrid capacitors combine the properties of capacitors and batteries. One electrode uses the capacitive mechanism, the other the battery-type redox processes. Scientists have now scrutinized ...

In his excellent discussion of Case 8-2001 (March 15 issue), 1 Dr. Wong did not mention that the low anion gap is another helpful clinical clue. On the day of admission, the patient had a relatively ...
