Question

The test for NH4+ is always performed on a portion of the original solution (with NaOH or Nessler's reagent), and not on the filtrate from later groups, because

Accepted Answer

NH4Cl, NH4OH and (NH4)2CO3 are added as reagents during the group separation, so ammonium ions would always be found

Answer

NH4+ is precipitated along with group I as NH4Cl

Answer

NH4+ is oxidised by H2S in group II

Answer

the filtrate after group V is always strongly acidic and gives no NH3

The test for $NH X_{4} X^{+}$ is always performed on a portion of the original solution (with $NaOH$ or Nessler's reagent), and not on the filtrate from later groups, because
