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 |
|---|---|---|
| Salt solution + dilute HCl | White precipitate | Pb²⁺ may be present |
| Confirmatory Tests | ||
| Potassium Iodide Test Salt solution + KI solution | Yellow precipitate | Presence of Pb²⁺ is confirmed |
| Potassium Dichromate Test Salt solution + K₂Cr₂O₇ solution | Yellow precipitate | Presence of Pb²⁺ is confirmed |
The given salt contains Pb²⁺ ions as cation and NO₃⁻ ions as anion. The salt is Pb²⁺NO₃⁻.
