ppt forms which is soluble in aq ammonia
silver nitrate (aq) mixed with iron(II) chloride (aq), grey ppt
forms which is INsoluble in aq ammonia
Which statements are correct abt one or both reactions?
1) silver ions acts as oxidizing agent
2) ammonia form soluble complex with silver metal
3) iron (II) ion acts as catalyst in decomposing silver
chloride
my ans is option 1 and 2
ans given is option1 only
The "silver metal" in the statement "ammonia form soluble complex
with silver metal" refers to Ag in the reduced state, not Ag+ that
you're thinking of (which accepts dative bonds from ammonia
ligands to form the diamine silver(I) ions of Tollen's
reagent).
