Solution Summary

Cl- concentration in surface water analysis has been questioned. The solution finds the correct concentration of chlorine ions necessary for charge balance.

Solution Preview

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 ...
