Question

Mixture x=0.02 mol of [co(nh3)5so4]br and 0.02 mol of

Answer 1

1.0 L of mixture X contain 0.01 mole of each

[(Co(NH3)5 SO4)]Br an [Co(NH3)5 Br]SO4.

And with AgNO3, only [(Co(NH3)5 SO4)]Br reacts to give AgBr precipitate as

[Co(NH3)5 SO4]Br + AgNO3→ [Co(NH3)5 SO4]NO3 + AgBr 1.0 mol 1.0 mol excess
