Why are only `Pb^(2+),Ag^(o+)` and `Hg_(2)^(2+)` ions precipitated in group I? |
|
Answer» Out of all the chlorides those of `Pb^(2+), Ag^(o+)` and `Hg_(2)^(2+)` are insoluble HCl is the reagent group I. thus chlorides of `Pb^(2+),Ag^(o+)` and `Hg_(2)^(2+)` are precipitated I group I. `AgNO_(3)+Hcltounderset(("white ppt."))(AgCl(s))+HNO_(3)` Other cations remain in solution because their chlorides are soluble. |
