Understanding why ocean water is salty but river water isn’t is a fascinating topic, and one that has intrigued scientists ...

This animation shows a very simplified model of how sodium and chloride ions are formed. Note: In order to simplify the model of ionic bonding, a single atom of sodium and chlorine are shown. In ...

The negative areas of the water molecules surround the positive sodium ions. As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves.

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

Researchers have engineered ultra-thin ion-selective membranes with sub-2-nanometre channels, enabling more efficient clean energy systems such as flow batteries, osmotic power generators, and ...

When salty water does freeze, the ice crystals that form are made of pure water with the sodium and chloride ions pushed out into the remaining liquid. At cold enough temperatures, ...

Sodium-ion batteries use common sodium chloride and biomass as main raw materials, reducing the reliance on scarce metals like lithium and cobalt. Life cycle assessment shows sodium-ion batteries ...

Sodium, Potassium and zinc ... Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater ...

Each molecule of these salts produces three ions—one of either magnesium or calcium plus two of chloride—to interfere with ice formation, while sodium chloride breaks down into only two.
