Ca2+, Na+, K+, NH4+, SO42-, Cl-, NO3-
3
Q
Salinity
A
Is the degree of mineralization of water
4
Q
Salinity helps govern….
A
Along with T and pressure, salinity helps govern physical properties of water, like density and heat capacity. Salts can be bad for freshwater plants and animals, and an overload of salts occurs when evaporation is high
