Chloroacetic acid pKa: 2.85. Most reactions take advantage of the high reactivity of the C–Cl bond. A buffer solution is prepared by mixing 0.0800 mol of chloroacetic acid (pKa 2.865) with 0.0400 mol of sodium chloroacetate in 1.00 L of water. 0000000751 00000 n 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. 0000002830 00000 n Chloroacetic acid is a weak acid, and thus, dissociates partially in water to form hydronium and acetate ions. 0000010457 00000 n <]>> 0000002363 00000 n 0000003318 00000 n Using this: [ClCH2COOH]=1.12-0.038=1.082M @ equilibrium.
