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 + NaOH solution | White precipitate | Mg²⁺ may be present |
| Confirmatory Test | ||
| Magneson Test Salt solution + Magneson reagent + NaOH solution | Blue lake formation | Presence of Mg²⁺ is confirmed |
The given salt contains Mg²⁺ ions as cation and NO₃⁻ ions as anion. The salt is Mg²⁺NO₃⁻.
