Why is salt not soluble in oil but not in water?

Answer 1

Well, isn't that just a happy little question! You see, salt dissolves in water because water is a polar solvent, while oil is nonpolar. Since salt is made up of ions with positive and negative charges, it needs a polar solvent like water to dissolve and separate those ions. Oil, being nonpolar, cannot break apart those salt ions, so salt remains insoluble in oil. Just like in painting, it's all about finding the right combination of elements for things to come together beautifully.

Answer 2

water is a polar molecule .so there create a electric dipole between hydrogen (positive) and oxygen(negative).water dissociates the ionic bond of the salt forming positive and negative ions .thus result a strong interaction between water and salt

Answer 3

The answer is very simple.Sugar and Salt dissolve in water but oil does not because sugar and salt are lighter in weight than water but oil is much heavier than the actual volume of water.That's why it doesn't dissolver.

Answer 4

The general rule is "like dissolves like." Water is a polar substance and caries charges. The chemical formula for table salt is NaCl. It is an ionic compound. As you put salt in water the salt and water molecules begin breaking apart into charged particles. The positively charged water molecules surround the negatively charged Cl atoms. The negatively charged water molecules surround the positively charged Na atoms. The separated Na and Cl molecules disperse within the water, therefore dissolving.

Oil does not contain any charges, resulting in it being non-polar. Therefore, because oil does not carry the charges necessary to break up the NaCl bond, the salt will not dissolve in oil. This is essentially the same reason that oil and water do not mix. Water is polar and oil is non-polar.

Answer 5

Water is a polar molecule and oil is a nonpolar molecule. Water can only dissolve other polar substances and many ionic compounds, but not nonpolar substances. Basically, the rule is "like dissolves like."

Answer 6

Salt is soluble in water because water molecules are polar, allowing them to break apart the ions in salt and dissolve it. On the other hand, oil molecules are non-polar, so they cannot break apart the ionic bonds in salt. This is why salt is not soluble in oil.

Answer 7

Salt is soluble in water because water is polar. Salt is not soluble in oil because oil is nonpolar. Salt dissociates into sodium and chloride ions in water.
