A water sample has 122 mg/L of bicarbonate ion (HCO3-), 30 mg/L of carbonate ion (CO3-). a. Please find the pH at equilibrium graphically. b. How would pH change if NaOH is added? c. What is the pH range corresponding to molar HCO3- concentration being 10 times higher than and equal to molar CO3- concentration. H: 1 g/mole, C: 12 g/mole, O: 16 g/mole Ka1 = 10-6.35 Ka2 = 10-10.33 (Please do the solution correctly. I asked the same question n CHEGG before , but the wrong solutions came. Please don't solve if you don't know for sure.)
