If you had a substance that water will not dissolve, then which of the following compounds would you choose to dissolve this substance?

A. Vegetable oil

B. Any polar substance

C. Any ionic substance.

D. None of the above will work.

A. Vegetable oil

Explanation:

Solubility is determined by the principle, "like dissolves like".

i. e., if a compound is polar then it will dissolve in a polar compound only, and

if a compound is non - polar then it will dissolve in a non - polar compound only.

Hence, from the question,

A. Vegetable oil is a non polar compound,

B. Polar compound

C. ionic compound, is a polar compound.

Since, wate is polar in nature, hence it will get dissolved in a only polar compound,

Therefore,

Water will not get dissolved in vegetable oil, being it a non - polar compound.
