chemical test to distinguish between sodium carbonate and sodium bicarbonate
How can you tell the difference between carbonate and bicarbonate?
The key difference between carbonate and bicarbonate is the charge on the compounds; carbonate has -2 charge and bicarbonate has -2 charge.
The molecular weights are also different because of the presence of Hydrogen atoms on bicarbonate which is 61 g/mol whereas carbonate is 60 g/mol.12 août 2021How do you determine carbonate and bicarbonate?
Firstly phenolphthalein is added as an indicator.
On adding the slandered acid drop – wise, the pink colour disappears when all the carbonate in the sample water are converted to bicarbonates.
At this stage methyl orange is added as an indicator.
Now the colour of the sample water is yellow.What is the chemical test to distinguish between sodium carbonate and sodium bicarbonate?
The phenolphthalein indicator can be used to distinguish aqueous solutions of sodium carbonate and sodium bicarbonate.
The aqueous solution of sodium bicarbonate containing phenolphthalein indicator is colurless whereas the aqueous solution of sodium carbonate containing phenolphthalein indicator is pink in colour.One important chemical test to differentiate carbonate and bicarbonate is MgSO4 test.
When carbonate salt is reacted with MgSO4, a white salt precipited while bicarbonate salt on reacting with MgSO4, not only a white salt precipited but also a brisk effervescence occur.18 juil. 2016
