To determine the presence of anion and cation in the given salt
| Experiment | Observation | Inference |
|---|---|---|
| Salt + dilute H₂SO₄ | No reaction | Dilute H₂SO₄ group is absent |
| Salt + Conc H₂SO₄ | No reaction | Conc H₂SO₄ group is absent |
| Confirmatory Test | ||
| Barium Chloride Test Salt solution + Dil HCl + BaCl₂ solution | White ppt insoluble in conc. HCl | Presence of SO₄²⁻ is confirmed |
| Experiment | Observation | Inference |
|---|---|---|
| Flame test | Golden yellow flame | Presence of Na⁺ is indicated |
| Confirmatory Test | ||
| Zinc Uranyl Acetate Test Salt solution + Zinc Uranyl Acetate reagent | Yellow crystalline precipitate | Presence of Na⁺ is confirmed |
The given salt contains Na⁺ ions as cation and SO₄²⁻ ions as anion. The salt is Na⁺SO₄²⁻.
