If a buffer solution is 0.120 m in a weak base (kb = 6.2 × 10-5) and 0.520 m in its conjugate acid, what is the ph?
Answers: 1
![p_{OH}=P_{K_b}+log\frac{[\text{ conjugate acid}]}{[\text{ weak base}]}](/tpl/images/0039/8301/7fbd7.png)
.![p_{K_b}=-log[K_b]=-log(6.2\times 10^{-5})=4.208](/tpl/images/0039/8301/ead14.png)
