Most ionic compounds are soluble in water. This is because polar water molecules have a strong attraction for charged ions.The charged ions become solvated as they dissociate into water.
Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.
Kerosene is a non-polar organic solvent and dissolves non-polar covalent compounds. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent. ... For example, ionic compounds are insoluble in hexane.

Ionic compounds are soluble in Water because:
water is a polar covalent compound so it reduces the inter ionic attraction. Hence ionic compounds are soluble in water.
But kerosene oil is a non polar covalent compound so it cannot break the force of attraction as result ionic compounds are insoluble in kerosene
