# An aqueous solution contains 0-34 M ammonia- One liter of this soluti.docx

An aqueous solution contains 0.34 M ammonia .

One liter of this solution could be converted into a buffer by the addition of:

(Assume that the volume remains constant as each substance is added.)
0.34 mol Ba(NO 3 ) 2
0.35 mol NH 4 NO 3
0.35 mol HNO 3
0.17 mol KOH
0.17 mol HNO 3
Solution
Option B 0.35 mol NH4NO3. Since the mixture is an example for basic buffer and it has the following combination of weak base (NH3) & Salt of weak base with strong acid (HNO3)
Basic buffer : NH3/NH4NO3
.
