Calcium carbonate is relatively insoluble in water, but. dissolves more readily in water containing significant. levels of dissolved carbon dioxide.1. The concentration of calcium ions (Ca2+) in freshwater is found in a range of 0 to 100 mg/L, and. usually has the highest concentration of any freshwater cation. A level of 50 mg/L is. recommended as the upper limit for drinking water.
The pH of water determines the solubility (amount that can be dissolved in the water) and biological availability (amount that can be utilized by aquatic life) of chemical constituents such as nutrients (phosphorus, nitrogen, and carbon) and heavy metals (lead, copper, cadmium, etc.).ne of the most popular school science projects is to take the pH of water from different sources. Chances are your school (and certainly not you) does not have an electronic pH meter lying around, but you can still get an estimate of pH by using litmus paper.
