Solution
| Sodium Sulphite | Sodium carbonate |
| Sodium sulphite is the sodium salt of sulphurous acid having molecular formula Na2SO3, can be made by dissolving NaOH in H2SO3. In Sodium sulphite, the oxidation state of Sulphur is +4. | Sodium carbonate (Na2CO3) will effervesce when dilute acid is added and a colourless, odourless gas (carbon dioxide) will be given off which, if bubbled through lime-water, will turn it cloudy. |
