0.31M ammonia+ 0.32M ammonium nitrate is the good buffer systems. because ammonia(a weak base) molecules can react with any excess hydrogen ions introduced by strong acids:
NH3(aq) + H+(aq) = NH4 +(aq)
while ammonium ion can react with any hydroxide ions introduced by strong bases:
NH4 +(aq) + OH-(aq)= NH3(aq)+ H2O(l)
and we know a good buffer system is a solution that resists sudden change in pH.
