Why does table salt NaCl dissolves in water but not cooking oil?

Answer 1

Table salt (NaCl) dissolves in water because the polarity of the water (H2O) breaks the ionic bond betwen the Na and Cl. The two hydrogens are slightly positively charged and so they turn towards the negative chloride, and in the process they brake the ionic bond.The slightly negative oxygen turns towards the sodium and again brakes the ionic bond.

Oil is a non-polar substance, so the

water doesnt have anything to hold on to because all the molecules in oil have a neutral charge.

This explenation is as simple as it gets, if you want to learn more you should probably go to a chemistry web site.

Answer 2

NaCl is a crystalline lattice formed from sodium and chloride ions. It dissolves well in water as it has soluble ions (hydroxonium and hydroxide ions). Cooking oil is a mix of hydrocarbons which has covalent molecules which won't provide ions in the solution.

NaCl is made by bonding Na+ ions and Cl- ions. In aqueous medium,NaCl is broken into Na+ and Cl- ions and these ions make bonds with charged water molecules. These ions does not make bonds with uncharged oil molecules. So NaCl does not dissolve in cooking oil.

Answer 5

Sodium chloride and water are polar compounds; oil is not a polar compound.
