Consider the given acid ionization constants. identify the strongest conjugate base.
WARRIOR [948]
The question is incomplete. Complete question is:
<span>Consider the given acid ionization constants. identify the strongest conjugate base.
</span>HNO2(aq) 4.6×10−4
HCHO2(aq) 1.8×10−4
HClO(aq) 2.9×10−8
HCN(aq) 4.9×10−10
.........................................................................................................................
Correct Answer: option 4: HCN(aq) 4.9×10−10

Reason: 
According to Lowry and Bronsted theory of acid and base. Stronger the acid, weaker will be the conjugate base.

In present case, ionization constant is highest of HCN i.e. 4.9×10^{-10}. This signifies that, it is the strongest acid. Hence, conjugate base associated with this acid (i.e. CN^{-}) is the weakest.
