Tests for anions

Anions are negatively charged ions such as halides (Cl^–, Br^–, I^–), sulfates (SO₄^2-), and carbonates (CO₃^2-). In this video, we will discuss the test tube tests for these ions, which all relate to the required practical activity in this topic: use of chemical tests to identify the ions in unknown single ionic compounds covering the both metal ions (cations) and non-metal ions (anions).
