To determine the presence of anion and cation in the given salt
| Experiment | Observation | Inference |
|---|---|---|
| Salt + Conc H₂SO₄ | Colorless gas evolves that etches glass | F⁻ may be present |
| Confirmatory Test | ||
| Calcium Chloride Test Salt Solution + CaCl₂ solution | White gelatinous ppt forms | Presence of F⁻ 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 F⁻ ions as anion. The salt is Pb²⁺F⁻.
