This muscle is used for the everyday functions of swimming and maintaining position in a current. The white muscle is brought into play only when additional bursts of energy are required. A word derived from a combination of the words Reduction and Oxidation . The higher the reading, the higher the availability of oxidising agents in the water. The process where a molecule gain an electron.
Reduction applies only to chemical reactions where a transfer of electrons occurs.
The opposite of oxidation . Refractometer Device for measuring the salinity of water. More accurate and easy to use in the field than a hydrometer. Uses light refraction through a lens. The light refracts to a greater or lesser degree in different salinities.
