A chemical analysis of a surface water yields the following data:
Ion Concentration mg/L
Problem: The Cl^- concentration in the water analysis given has been questioned. What concentration of Cl^- (mg/L) would make the cations and anions balance?© BrainMass Inc. brainmass.com July 21, 2018, 11:40 am ad1c9bdddf
To calculate charge balance, first you need to convert the concentrations to meq/L .
meq/L is also equal to millimoles of charge per liter (mM+/L or mM-/L depending on valence).
To do this, you need to know the molecular weight and charge of each ion, and whether it is positive ...
Cl- concentration in surface water analysis has been questioned. The solution finds the correct concentration of chlorine ions necessary for charge balance.
