Problem $6-12($P$371).$ It is Revised below:

Prepare a bar chart$/$graph for the Lake Michigan water analysis on the CATIONS: $C{a}^{2+},M{g}^{2+},$ and $N{a}^{+}$; and ANIONS: $HC{O}_3^{-}($Bicarbonate$),C{l}^{-}$and $S{O}_4^{2-}$

Based on the bar chart$/$graph$,$ figure out TH$,$ CH and NCH$.$

$6-12.$ Prepare a bar chart of the Lake Michigan water analysis shown below. Because all of the constituents were not analyzed, an ion balance is not achieved. For the estimate of the $C{O}_2$ concentration, ignore the carbonate alkalinity.
