Problem: Determine the percent ionization of a 0.130 M HCN solution.

FREE Expert Solution

We have to determine the percent ionization of a 0.130 M HCN solution.

A weak acid ionizes reversibly in its aqueous solution.

HA + H2O H3O+ + A-

The percent ionization of a weak acid is calculated by this formula.

Percent ionization = [H3O+][HA]×100%


We will solve this problem through these steps:

Step 1: Write an equation for the dissociation of HCN.

Step 2: Write an expression for the Ka.
