Identification of Ions & Gases
Part 1 - Identification of Cations
The chapter Identification of Ions & Gases is explained in this session.
The following concepts are explained:
♦ Procedure for identification of cations
♦ Tests for Ca2+, Al3+ and Zn2+ ions using aqueous sodium hydroxide (NaOH)♦ Tests for Fe2+, Fe3+, Cu2+ and Cr3+ ions using aqueous sodium hydroxide (NaOH)♦ Demonstrations (videos) of the above tests♦ Test for ammonium ion, NH4+ using aqueous sodium hydroxide (NaOH)♦ Tests for Ca2+, Al3+ and Zn2+ ions using aqueous ammonia solution (NH3)♦ Tests for Fe2+, Fe3+, Cu2+ and Cr3+ ions using aqueous ammonia solution (NH3)♦ Demonstrations (videos) of the above tests♦ Further notes on identification of cations (Qualitative notes from syllabus)The exercise file section contains notes on Identification of Ions - Part 1
