To determine the presence of anion and cation in the given salt
| Experiment | Observation | Inference |
|---|---|---|
| To dry salt, dilute H₂SO₄ is added | No reaction | Dilute H₂SO₄ group is absent |
| Salt + Conc H₂SO₄ | Colorless gas with pungent smell evolves | Cl⁻ may be present |
| Confirmatory Test | ||
| Silver Nitrate Test Salt Solution + Dilute HNO₃ + AgNO₃ solution | White ppt soluble in NH₄OH | Presence of Cl⁻ 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 Cl⁻ ions as anion. The salt is K⁺Cl⁻.
