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 ...

A cation refers to an atom or a group of atoms that bear one or multiple positive electric charges. An anion refers to an atom or a group of atoms that bear one or multiple negative electric charges.

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 ...

L. J. Sanger, M. F. Billett and M. S. Cresser Journal of Applied Ecology publishes novel papers that apply ecological concepts, theories, models and methods to the management of biological resources ...

A new thermogalvanic device uses nanoparticles to control ion flow, allowing it to convert waste heat to electricity and store the energy without external batteries.

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 ...

In a boreal forest catchment in the Experimental Lakes Area in northwestern Ontario, wildfire caused an increase in the concentrations of strong acid anions and base cations of the stream. In the ...
