A weak acid has a dissociation constant of Ka = 0.025.
(a) Calculate the degree of dissociation for a 0.094 m solution of this acid using the Debye-Huckel limiting law.
(b) Calculate the degree of dissociation for a 0.094 m solution of this acid that is also 0.200 m KCl from the Debye-Huckel limiting law using an iterative calculation until the answer is constant in the second decimal place.
(c) Repeat the calculation (b) using the value of \(\gamma\pm\) = 0.718 for KCl.
This problem is from the Engel-Reid Physical Chemistry textbook, 3rd edition. Problem 10.5. Chegg does not have solutions for this chapter...
