in seawater in terms of the conditional stability constants of metal complexes and the corresponding ligand concentration. Based on the conditional stability constants of organic Cu(II) complexes,
In the original version of the metric system the base units could be derived from a specified length (the metre) and the weight [mass] of a specified volume ( 1â7003100000000000000â 1000 of a cubic metre) of pure water.
The base units are those used to measure basic amounts, such as the kilogram which is the basic unit of mass, or the meter which is the basic unit of distance. Derived unitsâ¦ are the combination of base units such as velocity which requires the measurement of both a distance and a time measurement.
