Question
Iodous acid (HIO,) is a weak acid that dissociates in water as follows.
HIO,(aq) + H,0(1)=H;0*(aq) + I02 (aq)
The acid-dissociation constant (K) for iodous acid is 3.2x10-5. Calculate the percent ionization (percent
dissociation) if the initial concentration of iodous acid was 0.35 M.
Step 1 of 5
Recall the relationship between an acid's dissociation constant (K) and its percent ionization (percent
dissociation).
[H,0*1e
equilibrium x 100%
% ionization of an acid =
[HA]initial
In this equation, [HA]nitial is the initial concentration of the acid in molarity and [H,0*]equilibrium is the
concentration of H,0+ ions at equilibrium in molarity. Before calculating the percent ionization, the K,
of
iodous acid must be used to find the following.
O [H,0*]initial
O [HAJequilibrium
[HA]initial
[H,0*]equilibrium
Step 2 of 5
Write the acid dissociation constant expression for this given reaction.
HIO,(aq) + H,0(1) =H,0*(aq) + I0, (aq)
The acid dissociation constant expression for the reaction of HIO, with water is the following. (Concentration
equilibrium expressions take the general form: K. = [C]° / [A]ª . [B]°. Subscripts and superscripts that
include letters must be enclosed in braces {}.)

Note that the concentrations expressed in the acid dissociation constant are equilibrium concentrations, which
must be determined.
Write the expression for the acid-dissociation or base-dissociation constant for a specified weak acid or base.
