A mixture of sodium carbonate and sodium bicarbonate was subjected to heating. Some loss in weight was found. How does this information help us to find out the composition of mixture?

Text Solution

Verified by Experts

Between sodium carbonate and sodium bicarbonate, only sodium bicarbonate decomposes to given sodium carbonate, `CO_(2) and H_(2)O`. The gaseous products `(CO_(2) and H_(2)O)` escape out into the atmosphere. Therefore, an apparent loss in weight occurs during the reaction.
This loss in weight corresponds to the amount of gaseous products formed . Fromed the mass of gaseous products formed, amount of sodium bicarbonate in the mixture can be obtained, and thus composition of the mixture of the mixture can be found out.
