Question

Vinegar dissolves in water. State whether the statement is true or false.

Answer 1

Hint: The nature of the substance in the water can be decided by the ability to react with water, if the compound is hydrophilic then it will be soluble in water and if the compound is hydrophobic then it will not be soluble in water. But sometimes, the compounds which are hydrophilic are still not soluble in water.

Complete answer:
There are many properties of the substance and one of the properties is the solubility of the given compound in the water, as water is a universal solvent. If the compound is hydrophilic then it will be soluble in water and if the compound is hydrophobic then it will not be soluble in water.
The given compound in the question is vinegar, and vinegar is an aqueous solution of acetic acid and some flavors are also added to it. The product vinegar is hydrophilic in nature, which means it likes water. As a result, it doesn't dissolve in water but absorbs water on a molecular level, giving the appearance of a soluble solution.
When water is dissolved in vinegar, the vinegar molecules incorporate the water molecules into their molecular structure, becoming a part of themselves. As a result, if the question is whether vinegar dissolves in water or not, scientifically speaking, vinegar does not dissolve in water; rather, it absorbs water molecules.
So, the given statement in the question “Vinegar dissolves in water” is false.

Note:
For most of the organic compound the solubility of the compound depends on the length of the hydrocarbon part in the compound, if the compound has a large alkyl group then the solubility will be low.
