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 ...

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 ...

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 ...

Huang Feihe at Zhejiang University, Jonathan Sessler of the University of Texas at Austin, and colleagues reported a novel cation recognition mode which mimics the biological allosteric effect and ...

When the dilution or mixing of the salt or ionized forms of organic drugs results in precipitation, the most likely cause is formation of the nonionized drug forms. Yet, for example, when ceftriaxone ...

Chromatography is the science of separating molecules of interest to identify, quantify or even purify them. Properties of the target molecules such as their solubility, size or hydrophobicity give ...
