    FeSO_(4) solution mixed with (NH_(4))_(2)SO_(4) solution (in molar ratio 1 : 1) gives the test of Fe^(2+) ion but CuSO_(4) solution mixed with liquid NH_(3) (in the molar ratio 1 : 4 ) does not give the test of Cu^(2+) . Explain why.

    Sodiumfusion Extract is acidified with HNO_(3) and then treated with AgNO_(3) solution if the organic compound contains halogens. In which of halogen gives white precipitate & which is soluble in NH_(4)OH solution. Second halogen gives yellow ppt and which is insoluble in NH_(4)OH solution. Identify the halogens respectively.
