1. Aqueous solutions should be electrically neutral. In other words, cations and anions should be balanced with each other (charge balance) The following table shows the composition of typical seawater. 1. Set up a charge balance equation for the seawater. (b) Analyze the seawater whether is neutral or not. Note that the seawater constituent are expressed in mass concentrations. Constituent mg/kg (ppm) Sodium (Na*) 10,500 1,350 400 380 Magnesium (Mg2) Calcium (Ca2") Potassium (K) Chloride (Cl) Sulfate (SO2) Bicarbonate (HCO3)...
