How can sodium carbonate and sodium sulphite be identified? |
|
Answer» carbonate (Na2CO3) will effervesce when a 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. Sodium SULPHITE (Na2SO3) will effervesce when a dilute acid is added giving off a colourless gas with a choking smell (sulphur dioxide), which, if bubbled through acidified DICHROMATE solution will turn it green.I think this will help you. |
