What is the pH of a buffer made from 0.130 mol of HCNO (Ka = 3.5 × 10⁻⁴) and 0.410 mol of NaCNO in 2.0 L of solution?
Answers: 1
![pH=pKa+log(\frac{[base]}{[acid]} )](/tpl/images/0734/8563/33848.png)
![[base]=\frac{0.410mol}{2.0L}=0.205M](/tpl/images/0734/8563/eabfc.png)
![[acid]=\frac{0.130mol}{2.0L}=0.065M](/tpl/images/0734/8563/e375b.png)
