If 0.10 m solution of hclo2 is allowed to come to equilibrium, the percent of the acid molecules that is ionized is 29%
We have
HClO2 = 0.1 mole = 0.012
HClO + H2O ⇄ ClO₂⁻ + H₂O
Ka = 0.1α x 0.1α / 0.1(1-α)
= 0.1α²/1-α = 0.12
We have to form a quadratic equation from the above
0.1α² = 0.012 - 0.12α
We write the equation to be
0.1α² + 0.012 - 0.12α = 0
To solve the equation above, the quadratic formula calculator was used.
alpha = 0.29
This is 29 percent. Therefore the percentage of ionization is 29%.
<h3>What is ionization?</h3>This is the process through which neutral ions are chraged to become electrically charged.
