Human cells dwell in salt water. Their well-being depends on the ability of the body to regulate the salinity of extracellular fluids. By controlling water intake and excretion, the osmoregulatory ...

Chemical equations can be written to describe ... a common acid like nitric acid and a common alkali - sodium hydroxide. When they react water and a salt called sodium nitrate is produced.

This is water retention, and it causes puffiness and swelling. It can be triggered by many different things. We all need sodium. It plays an important part in regulating blood pressure and fluid ...

Here we suggest that the initial process enabling the alkali metal explosion in water is, however, of a completely different nature. High-speed camera imaging of liquid drops of a sodium/potassium ...
