Asolution of 0.18mol of the chlorine salt of protinated atropine (ah+), a weak organic base, in 1.0l of solution has ph = 5.20.
find the kb of atropine (a).
Answers: 1
of atropine is 
.
![[AH^+]=\frac{0.18 mol}{1 L}=0.18 M](/tpl/images/0486/0070/22678.png)
![[A]=[H^+]](/tpl/images/0486/0070/54eaa.png)
![5.20=-\log[H^+]](/tpl/images/0486/0070/190d7.png)
![[H^+]=6.3\times 10^{-6} M](/tpl/images/0486/0070/e0a1a.png)
for atropine is given as:![K_a=\frac{[A][H^+]}{[AH^+]}](/tpl/images/0486/0070/0828b.png)
