Question

The solvent used to prepare aqueous solutions is:

• A. Water
• B. Kerosene
• C. Petrol
• D.

Hint:

Remember, aqueous solutions specifically use water as the solvent.

Answer 1

The Correct Option is A

The process of preparing aqueous solutions involves dissolving a substance, known as the solute, in a solvent. In chemistry, an aqueous solution is specifically a solution where the solvent is water. This is because 'aqueous' implies that water is present, derived from the Latin word 'aqua', meaning water.

Hence, among the given options:

• Water: This is used to prepare aqueous solutions, as it is the solvent in such solutions.
• Kerosene: This is a hydrocarbon and is not used in aqueous solutions as a solvent.
• Petrol: Like kerosene, petrol is also a hydrocarbon and not used in aqueous solutions.

Therefore, the correct solvent for preparing aqueous solutions is Water.

Answer 2

Aqueous comes from the Latin word for water, so the question is really asking which of the listed liquids is water itself, since that is the only solvent that produces an aqueous solution by definition. Let's go through the options.

1. Water: This is the solvent that defines an aqueous solution. Any solute dissolved in water gives an aqueous solution, so this is the correct choice.
2. Kerosene: Kerosene is a hydrocarbon fuel, not water, so a solution made with kerosene as the solvent would be non-aqueous.
3. Petrol: Petrol is also a hydrocarbon mixture, and like kerosene it does not contain water, so it cannot form an aqueous solution either.
4. (blank option): No liquid is named here, so this choice does not offer an alternative solvent to consider.

Since only water fits the definition of the solvent in an aqueous solution, it is the answer.

So the correct answer is water.
