In the qualitative analysis scheme for metal ions,how are the Analytical Group I cations separated from the other cations? A)by addition of HCl,forming insoluble metal chlorides B)by addition of H₂SO₄,forming insoluble metal sulfates C)by addition of H₂S in acidic solution,forming insoluble metal sulfides D)by addition of H₂S in basic solution,forming insoluble metal sulfides or hydroxides E)by addition of (NH₄)₂CO₃ or (NH₄)₃PO₄,forming insoluble metal carbonates or phosphates
