Chloroacetic acid, ClCH2COOH, has a pKa of 2.87. The ICE table for this would be (in HA-->H+ +A-): Plugging the ICE equilibrium numbers into the equilibrium expression: ((x)(x)/(1.12-x))=0.00135, which translates to: ((x^2)/(1.12-x))=0.00135, which in quadratic form equals: Using the quadratic equation, I obtain the following roots: Considering these numbers, X=0.038. 0000003318 00000 n [H3O+]= MpH=[ClCH2COO- ]= M[ClCH2COOH]= M2- A 0.037 M Solution Of A Weak Acid (HA) Has A PH Of 3.20.
