Question

why sodium chloride is soluble in water but not soluble in kerosene ?

Answer 1

Answer:

Sodium chloride is polar molecule. electronegativity difference between sodium and chlorine gives polarity to the sodium chloride molecule. mostly polar molecules will soluble in polar solvents and insoluble in non-polar solvents. water is polar solvent and kerosene is non-polar solvent.

Answer 2

• ☆sodium chloride is soluble in water because salt ( sodium chloride) is made from positive sodium ions bonded to negative chloride ions water can dissolve salt because the positive part of water molecule attracts the positive sodium ions polar molecules
• ☆but not in kerosene because
• petroleum which is a nonpolar hydrocarbon that does not mix with water salt in a high ionic substance which dissolves completely in water
