To determine the presence of anion and cation in the given salt
| Experiment | Observation | Inference |
|---|---|---|
| Confirmatory Test | ||
| Brown Ring Test Salt Solution + FeSO₄ + Conc H₂SO₄ (added carefully along the sides of the test tube) | Brown ring forms at the junction of two liquids | Presence of NO₃⁻ anion is confirmed |
| Experiment | Observation | Inference |
|---|---|---|
| Flame test | Lilac flame | Presence of K⁺ is indicated |
| Confirmatory Test | ||
| Sodium Cobaltinitrite Test Salt solution + Sodium Cobaltinitrite reagent | Yellow precipitate | Presence of K⁺ is confirmed |
The given salt contains K⁺ ions as cation and NO₃⁻ ions as anion. The salt is K⁺NO₃⁻.
