Interpretation: The reason behind the insolubility of mineral oil in water has to be explained.
Concept introduction: Different substances have different solubilities in water. Some are highly soluble while some are almost insoluble in water. The principle of “like dissolves like” is very crucial for analyzing the dissolution of a specific solute in different solvents.
Answer to Problem 9LC
Due to the non-polar nature of hydrocarbons present in mineral oil, it remains insoluble in water.
Explanation of Solution
As per the principle of “like dissolves like”, polar substances are most likely to be soluble in polar solvents. Likewise, non-polar substances are seen to be soluble in those solvents that are non-polar in nature. Water is a polar solvent. However, the mineral oil contains a mixture of hydrocarbons. Hydrocarbons are non-polar substances and hence, oil remains insoluble in water.
Mineral oil is not soluble in water due to the non-polar nature of constituent hydrocarbons.
