`FeSO_(4)` solution mixed with `(NH_(4))_(2)SO_(4)` solution in 1:1 molar ratio gives the test of `Fe^(2+)` ion but `CuSO_(4)` solution mixed with aqueous ammonia in 1:4 molar ratio does not give the test of `Cu^(2+)` ion. Explain why?

FeSO_4 solution mixed with (NH_4)_2SO_4 solution is 1:1 molar ratio gives the test of Fe^(2+) ion but CuSO_4 solution mixed with aqueous ammonia in 1:4 molar ratio does not give the test of Cu^(2+) ion. Explain why?

FeSO_4 solution mixed with (NH_4)_2SO_4 solution is 1:1 molar ratio gives the test of Fe^(2+) ion but CuSO_4 solution mixed with aqueous ammonia in 1:4 molar ratio does not give the test of Cu^(2+) ion. Explain why?

KI and CuSO_4 solutions when mixed give

Consider the following experiments and answer the questions at the end of it (A) When Fe(CN)_(2) solution is treated with KCN solution species formed no longer gives tests of Fe^(2+) and CN^(Θ) (B) When K_(2)SO_(4) solution is treated with A1_(2)(SO_(4))_(3) solution species formed gives tests of K^(o+),A1^(3+) and SO_(4)^(2-) Species formed in experiment A does not give test of Fe^(2+) and CN^(Θ) it is due to formation of .
