The barbituate pentobarbitone, which is used as an anesthetic in vertebrates, has a single ionizable group with a pka of 8.0. what percentage of protonated pentobarbitone will be present in a solution that has a ph of 8.7?
Answers: 1
![pH = pka + log [\frac{Base}{acid}]](/tpl/images/0081/8167/a2ea1.png)
![8.7 = 8.0 + log [\frac{B}{BH^{+}}]](/tpl/images/0081/8167/d8163.png)
![8.7 - 8.0 = log [\frac{B}{BH^{+}} ]](/tpl/images/0081/8167/388bf.png)
![0.7 = log [\frac{B}{BH^{+}}]](/tpl/images/0081/8167/08e91.png)
