- Homework Statement
- Which combination will produce an alkaline buffer

a. 0.1 mol ammonia & 0.05 mol sulfuric acid

b. 0.5 mol ammonia & 0.10 mol sulfuric acid

c. 0.1 mol acetic acid & 0.05 mol NaOH

d. 0.1 mol acetic acid & 0.50 mol NaOH

- Relevant Equations
- Henderson Hasselbach equation

THe answer is supposed to be (B) but I'm not understanding properly

I initially chose A - to form an alkaline buffer, the # mol of acid should be half of this. But this doesn't seem to be the case

I don't understand why the mol of base in this case should be 5x the mole of acid

your help is greatly appreciated, as always!
