. An analysis water from well No 9 of the Manhattan beach, California, water composition showed : pH=7.8; silica: 19.2 mg SiO2/liter; calcium = 60 mg Ca2+/liter ; magnesium = 29.16 mg Mg2+/liter; sodium=78.2 mg Na+ /liter; potassium 42.9 mg K+ /liter; bicarbonate= 292.8 mg HCO3 - /liter; sulfate=134.82 mg SO4 2- /liter; chloride = 99.4 mg Cl- /liter and nitrate =6.2 mg NO3 - /liter. The relative atomic masses are: Si=28; Ca=40; Mg=24.3; Na= 23; K=39; O=16; H=1; C=12; S=32; Cl=35.5; N=14. (a) Calculate the ionic balance (b) Is the water analysis satisfactory from the point of view of analytical accuracy? Justify your answer
