The Alkalinity Titration Curve

In Chapter 2, alkalinity was defined in terms of a model containing only CO₂ and NaOH in solution: (2.16) or (3.1) A = [ HCO 3 − ] + 2 [ CO 3 − ] + [ OH − ] − [ H + ] . https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315138770/962791b3-d4ad-4475-a58f-b9b3774ab45e/content/eq287.tif"/>
