Calculate the pH of the buffer that results from mixing 60.0 mL of 0.25 M HCHO2(pKa= 3.74) and 15.0 mL of 0.500 M NaCHO
Answers: 2
![pH=pKa+log(\frac{[Base]}{[Acid]} )](/tpl/images/0847/6909/0f602.png)
![[Base]=\frac{7.50x10^{-3}mol}{0.0750L}=0.1M](/tpl/images/0847/6909/511d1.png)
![[Acid]=\frac{1.5x10^{-2}mol}{0.0750L}=0.20M](/tpl/images/0847/6909/d9c97.png)
