www2.chem.uic.eduChloroacetic acid has a dissociation constant of K a = 1.38 10–3. (a) Calculate the degree of dissociation for a 0.0825 m solution of this acid using the Debye–Hückel limiting law. (b) Calculate the degree of dissociation for a 0.0825 m solution of this acid that is also 0.022 m in KCl using the Debye–Hückel

www.ccri.edupresent. Ka, the equilibrium constant for the reaction, is the dissociation constant of HA, and has a constant value at a given temperature. The species HA may be an organic acid, such as acetic acid, a hydrated metal cation, such as Cu(H2O)4 2+, ammonium ion, NH 4 +1 or an inorganic molecule or anion, like H 2CO3. Acid
