measured water sample has a SAR value of 12. The sample has the following composition (milliequivalent/mE) - Ca: 7.32, Mg: 2.5, Na: 27. You are required to reduce the SAR value to 5. How may mE of Calcium (Ca) would you be required to add to the sample?
I am not sure how where to begin. Do I halve the weight of Mg and Ca because they are 2+
