What is the ph of a solution containing 0.12mol/l of nh4cl and 0.03 mol/l of naoh (pka is 9.25)?
Answers: 1
![[NH_{4} Cl] = 0.12-0.03= 0.09 M\\](/tpl/images/0220/4078/cbd45.png)
![[NH_{3}] = 0.03 M](/tpl/images/0220/4078/07db8.png)
![pH = pKa + log\frac{[NH3]}{[NH4Cl]}](/tpl/images/0220/4078/3f7a5.png)
![pH = 9.25 + log\frac{[0.03]}{[0.09]}=8.77](/tpl/images/0220/4078/6b0b1.png)
