Question

Separating a mixture of NaHCO₃ and Na₂CO₃ using green chemistry involves:

a) Distillation
b) Precipitation
c) Filtration
d) Chromatography

Answer 1

The green chemistry method for separating a mixture of NaHCO₃ and Na₂CO₃ involves precipitation. Other methods like distillation, filtration, and chromatography may be used for separating different mixtures based on their properties.

Step-by-step explanation:

The green chemistry method for separating a mixture of NaHCO₃ and Na₂CO₃ involves precipitation.

Precipitation is a process in which a solid substance separates from a solution. In this case, the two substances, NaHCO₃ and Na₂CO₃, can be separated by adding a suitable reagent that forms a solid precipitate with one of the substances. The precipitate can then be filtered to separate it from the remaining solution.

Other methods like distillation, filtration, and chromatography may be used for separating different mixtures based on their properties, but in this specific case, precipitation is the most appropriate method.
