Question

A water sample is analyzed to determine concentrations of major ions with the following results:

Check for cation-anion balance. What is the percent imbalance (in any) for the cations and anions
for this sample? Is the analysis accurate? Why or why not?

Explanation / Answer

cation conc=100/23+60/39+50/40 *2+30/24 *2=10.886 mol of +charge anion conc =30/61+66/96 *2 +100/35.5 +120/95 *3 =8.418 mol of -ve charge per litre %imbalance =(10.886-8.418)/10.886 *100=22.67 % Analysis is accurate as we hav indivisually calculated the cationic and anionic charge
