Question
Which of the following equations correctly represents the charge balance of a typical freshwater
body?
a) [Ca²*]+ [Mg²*]+ [Na²*] = [HCO;²-]+ [co;²-]+ [so,²-]+[OH¯]
b) 2[Ca²*] + 2[Mg²*] + [Na²*] = [HCO;²-]+ 2[Co,²-]+ 2[so,²-]+ [0H¯]
c) 2[Ca²*]+ 2[Mg²*] + 2[Na²*] = [HC0,²-]+ [co,²-] + [so,²-]+ [0H¯]
d) 2[Ca?*] + 2[Mg²+] + [Na²*] + [HCo,²-] + 2[co,²-] + 2[so,²-] + [OH¯]
