To determine the presence of anion and cation in the given salt
| Experiment | Observation | Inference |
|---|---|---|
| Salt Solution + Universal Indicator | Solution turns blue or purple | OH⁻ may be present |
| Confirmatory Test | ||
| Phenolphthalein Test Salt Solution + Phenolphthalein indicator | Solution turns pink | Presence of OH⁻ 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 OH⁻ ions as anion. The salt is Pb²⁺OH⁻.
