Ag(CN)2- w/ N4HNO3 aqueous
« on: November 26, 2013, 09:55:45 AM »
If 1 mol of Ag(CN)2- (aq) is mixed with 2 mol of H4NNO3 (s), why would the the NH4 not react with the (CN)2-?

Do you mean why ligand CN- in Ag(CN)2-  cannot be replaced by NH3. What do you think, why?

Look at complex formation constants and check concentration of ammonia (not NH4+)
