The unit for this is DO. Dissolved oxygen in water helps to sustain life, such as fish or marine plants.

This means that near freezing water can hold twice as much dissolved oxygen as warm water. Colder water is better able to hold dissolved oxygen and it is therefore better able to sustain life. The expected limit of dissolved oxygen at normal sea level air pressure falls between that range of 15-8 mg/L, but the "safe" range falls closer to 15 mg/L.]]> 2017-10-19 17:39:20 UTC https://padlet.com/corkysgold3/77ml93fws2xr/wish/198795334 benmcnutt27 https://padlet.com/corkysgold3/77ml93fws2xr/wish/198799775 ^{http://www.ramp-alberta.org/river/water+sediment+quality/chemical/temperature+and+dissolved+oxygen.aspx}]]> 2017-10-19 17:46:41 UTC https://padlet.com/corkysgold3/77ml93fws2xr/wish/198799775 benmcnutt27 https://padlet.com/corkysgold3/77ml93fws2xr/wish/198800787 Solubility is the amount of a substance that can dissolve in a solution.
