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.

A few drops of dilute sodium hydroxide solution react to form a white precipitate with aluminium ions, calcium ions and magnesium ions. However, if excess sodium hydroxide solution is added: the ...

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 ...

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 ...

American Journal of Botany, Vol. 8, No. 9 (Nov., 1921), pp. 464-470 (7 pages) 1. Chromium has a different initial effect upon the permeability of Laminaria depending upon whether it occurs in the ...

Ion exchange (IEX) chromatography is a technique that is commonly used in biomolecule purification. It involves the separation of molecules on the basis of their charge. This technique exploits the ...

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 ...
