To determine the presence of anion and cation in the given salt
| Experiment | Observation | Inference |
|---|---|---|
| Salt + Dilute HCl | Colorless, odorless gas evolves with brisk effervescence | CO₃²⁻ may be present |
| Confirmatory Tests | ||
| Lime Water Test Pass the evolved gas through lime water | Lime water turns milky | Presence of CO₃²⁻ is confirmed |
| Magnesium Sulphate Test Salt solution + MgSO₄ solution | White ppt is obtained | Presence of CO₃²⁻ is confirmed |
| Experiment | Observation | Inference |
|---|---|---|
| Flame test | Golden yellow flame | Presence of Na⁺ is indicated |
| Confirmatory Test | ||
| Zinc Uranyl Acetate Test Salt solution + Zinc Uranyl Acetate reagent | Yellow crystalline precipitate | Presence of Na⁺ is confirmed |
The given salt contains Na⁺ ions as cation and CO₃²⁻ ions as anion. The salt is Na⁺CO₃²⁻.
