Chapter 17, Problem 4SAQ

Consider the given acid ionization constants and identify the strongest conjugate base.

Acid	Ka
HNO2(aq)	$\text{4}.\text{6}\times \text{1}{0}^{-\text{4}}$
HCHO2(aq)	$\text{1}.\text{ 8}\times \text{1}{0}^{-\text{4}}$
HClO(aq)	$\text{2}.\text{9}\times \text{1}{0}^{-\text{8}}$
HCN (aq)	$\text{4}.\text{9}\times \text{1}{0}^{-\text{8}}$

• NO₂^-(aq)
• CHO₂^-(aq)
• ClO^-(aq)
• CN^-(aq)
