A 1.00 L buffer consists of 0.10 M NH4Cl and 0.10 M NH3. Ka, NH4+ = 5.6 × 10-10. Find the pH of the buffer.
Added by James B.
Step 1
The reaction that occurs in the buffer solution is: NH4+ (aq) ⇌ NH3 (aq) + H+ (aq) The equilibrium constant expression for this reaction is: Ka = [NH3][H+] / [NH4+] We can rearrange this equation to solve for [H+], the concentration of hydrogen ions, which is Show more…
