(b) Which solution has a higher percent ionization of the acid, a 0.10M solution of HC2H3O2(aq) or a 0.010M solution of HC2H3O2(
boyakko [2]

Answer: The percent ionization is higher for 0.010 M solution of HC_2H_3O_2

Explanation:

HC_2H_3O_2\rightarrow H^+C_2H_3O_2^-

 cM           0M           0M

c-c\alpha        c\alpha          c\alpha  

So dissociation constant will be:

K_a=\frac{(c\alpha)^{2}}{c-c\alpha}

a) Given c= 0.10 M and \alpha = ?

K_a=1.8\times 10^{-5}

Putting in the values we get:

1.8\times 10^{-5}=\frac{(0.10\times \alpha)^2}{(0.10-0.10\times \alpha)}

(\alpha)=0.013

\%(\alpha)=0.013\times 100=1.3\%

b) Given c= 0.010 M and \alpha = ?

K_a=1.8\times 10^{-5}

Putting in the values we get:

1.8\times 10^{-5}=\frac{(0.010\times \alpha)^2}{(0.010-0.010\times \alpha)}

(\alpha)=0.041

\%(\alpha)=0.041\times 100=4.1\%

The percent ionization is higher for 0.010 M solution of HC_2H_3O_2
