Question

How do you separate a mixture of sodium chloride and potassium trioxonitrateV
​

Answer 1

See explanation

Step-by-step explanation:

We separate substances based on their important properties such as reaction to heat, solubility in water, magnetic properties, etc.

To separate sodium chloride and potassium trioxonitrateV, we need to heat the solution. KNO3 dissolves at a high temperature and crystallizes out as the solution is cooled.

Hence when we heat the solution, KNO3 dissolves, as we cool the solution, solid KNO3 crystals are obtained while NaCl remains in solution. We have now separated the two salts in the solution.

Note that the solubility of NaCl is almost independent of temperature.
