Na2CO3 + Ba(NO3)2 → BaCO3 + 2NaNO3
In this reaction, sodium carbonate and barium nitrate undergo a double displacement reaction, where the positively charged ions (sodium and barium) and the negatively charged ions (carbonate and nitrate) switch places to form new compounds.
The reaction proceeds as follows:
1. The sodium ions (Na+) from sodium carbonate and the nitrate ions (NO3-) from barium nitrate are attracted to each other due to their opposite charges.
2. Similarly, the barium ions (Ba2+) from barium nitrate and the carbonate ions (CO32-) from sodium carbonate are also attracted to each other.
3. As a result of these attractions, the sodium ions and nitrate ions combine to form sodium nitrate (NaNO3), while the barium ions and carbonate ions combine to form barium carbonate (BaCO3).
The products of this reaction, barium carbonate and sodium nitrate, are both white solids that are insoluble in water. Barium carbonate is a more stable compound compared to sodium carbonate and is commonly used in the production of other barium compounds and as a flux in the ceramics industry. Sodium nitrate, on the other hand, is used as a fertilizer and in the production of explosives.
