8. Using the ionization fraction table for carbonate species, indicate the fraction of all three species at the following pHs (to two decimal places): a) pH = 4 b) pH = 7 c) pH = 10 9. a) Using your fractions from 8b, and a total carbonate concentration of 2 mM, determine the alkalinity of the water in meq/L. Show all work. B) Repeat for 8c
