Alkalinity (Alk) has been defined as the acid-neutralizing capacity of a water, and we commonly use the following definition for the alkalinity of natural waters: Alk (eq/L) = [OH] + [HCO3] + 2[CO3]-[H]; where [X] = molar concentration of species X Given a 50-ml water sample required 5-mL standard 0.02 N sulfuric acid to reach the P-endpoint, and an additional 3-mL to reach the T-endpoint, report (a) P-Alk and T-Alk in eq/L and mg/L as CaCO3 (b) What can you say about the initial pH of the water? And what species contribute to the Alk? Given pk₁ = 6.35 and pK₂ = 10.33 for carbonic acid.
