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 ...

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 molecular movie has captured in detail the process of an anion transported across the cell membrane by a light-fuelled protein pump. Researchers have unravelled the mystery of how light energy ...

We rely on batteries now more than ever, from our phones and laptops to electric vehicles. But the ones powering today's ...

Resodec, § the exchange resin used in the patients described in this report, is an acrylic polymer of heavy molecular weight, whose carboxylic radicals can readily adsorb and release cations to which ...

This review describes a method of analyzing acid–base disorders that incorporates insights from the traditional, bicarbonate-centered model and the Stewart (or strong ion) model (Table 1). 1–6 ...

A new study at the University of Georgia has found a way to attack cancer cells that is potentially less harmful to the patient. Sodium chloride nanoparticles – more commonly known as salt – are toxic ...
