7. Given the following water analysis in mg/L: a. b. C. d. e. f. g. h. i. j. Ca=76.8 Mg2=20.54 Nat=11.72 K-1.67 SO4-37 HCO3-305.4 CI=13.25 pH=8.3 Convert the analysis into molal concentrations. Compute ionic strength. Compute the activity coefficient for each ion. Calculate the activity of each ion. Convert the analysis to meq/L. Is it a good analysis? Why or why not? Calculate the Kiap of CaSO4. Ksp of CaSO4 = 104.5. Can the water dissolve more CaSO4 ? Calculate the Kiap of calcium carbonate. K,, of calcium carbonate = 10-8.35. Can the water dissolve more limestone?
