Question

Why salt dissolve in water but not in kerosene

Answer 1

Salt is an ionic molecule. There exists electronegativity difference between Salt which gives polarity to the molecule. Thus salt is polar molecule. Generally polar molecules will soluble in polar solvents and insoluble in non-polar solvents. Non-polar molecules will soluble in non-polar solvents and insoluble in polar solvents. As sodium chloride is polar molecule it will be soluble in polar solvents like water. And insoluble in kerosene (as it is non-polar solvent).

★彡 why salt dissolve in water not in kerosene 彡★​



salt dissolve in water but not in kerosene because Kerosene comes from petroleum which is a nonpolar hydrocarbon that does not mix with water.

Salt is a high ionic substance which dissolves completely in water.

Therefore, combining the top 2 bullet points together, it should make sense why salt is very insoluble in kerosene.
