Sodium carbonate cannot be used in place of ammonium carbonate for the precipitation of the fifth group radicals becauseA. Sodium ions interfere with the detection of fifth group radicalsB. Concentrations of carbonate ions is very lowC. Sodium will react with acidic radicalsD. Magnesium will be precipitated |
|
Answer» Correct Answer - D When `(NH_(4))_(2)CO_(3)` is used then the concentration of `CO_(3)^(2-)` is comparatievely low but when `Na_(2)CO_(3)` is added then concentration of `CO_(3)^(2-)` increases so `Mg^(2+)` will be precipitated along with other V group radicals. |
