At 25°C, the equilibrium constant for the dissociation of acetic acid, K_a , is 1.75 × 10^–5. Using the Debye–Hückel limiting law, calculate the degree of dissociation in 0.150 m and 1.50 m solutions using an iterative calculation until the answer is constant in the second decimal place. Compare these values with what you would obtain if the ionic interactions had been ignored. Compare your results with the degree of dissociation of the acid assuming γ _± = 1.
