A chemical analysis of a water sample from a Lake in Idaho at 25C and pH 9.15 is given below in mg/L: Ca²⁺ 10 Mg²⁺ 113 Na⁺ 1630 K⁺ 134 HCO₃^- 1390 SO4^2- 264 Cl^- 1960

Using the given data. Calculate the activity coefficient for each ion using the Debye-Hckel Limiting Law (use a values of A = 0.5085). Then calculate the activity for each ion, using the activity coefficients that you calculated using the Debye-Hckel Limiting Law.
