Question

Give proper chemical tests to distinguish between na2co3 and nahco3 with equations

Answer 1

Answer:

Explanation:

One important chemical test to differentiate carbonate and bicarbonate is MgSO4 test.

Na2CO3+Mg2+⟶MgCO3↓(white)+Na+

NaHCO3+Mg2+⟶MgCO3↓(white)+H2O+CO2↑

When carbonate salt is reacted with MgSO4, a white salt is precipited while bicarbonate salt on reacting with MgSO4, not only is a white salt precipited but also a brisk effervescence occurs. The gas is detected by passing it through lime water.

Answer 2

Answer:

The chemical reactions those can be followed to distinguish between Na2Co3 and NaHCo3 is following. The major chemical test for differentiating carbonate and bicarbonate can be done through MgSO4 test. Na2CO3+Mg2+⟶MgCO3↓(white)+Na+ NaHCO3+Mg2+⟶MgCO3↓(white)+H2O+CO2↑.When the carbonate salt reacts with the MgSO4, the white salt is precipitated. On the other hand, in case of bicarbonate salt after reacting with the MgSO4, a brisk effervescence occurs along with the white precipitant. The gas can be detected through the lime water.
