Question:

Read the passage carefully and answer the Questions.

A homogeneous mixture of two or more than two components has uniform composition and properties. The binary solutions have two components, which may be solid, liquid or gas. The resultant solution has a larger amount of solvent and a smaller amount of solute. The amount of solute in a given amount of solvent decides the concentration of the resulting solution. The concentration can be expressed in various ways, like molarity, molality, normality and mole fraction.

Glucose dissolved in water and ethanol dissolved in water are examples of

Options:

Liquid solution and liquid solution, respectively.

Solid solution and liquid solution, respectively.

Solid solution and solid solution, respectively.

Liquid solution and solid solution, respectively.

Correct Answer:

Liquid solution and liquid solution, respectively.

Explanation:

The correct answer is Option (1) → Liquid solution and liquid solution, respectively.

  • Complete statement:
    Glucose dissolved in water and ethanol dissolved in water are examples of liquid solutions and liquid solutions, respectively.

    Reasoning:

    Solutions are classified based on the physical state of the solvent, because the solvent is present in the larger amount.

    1. Glucose dissolved in water
      Glucose is a solid and water is a liquid. Since the solvent (water) is liquid, the solution is called a liquid solution.

    2. Ethanol dissolved in water
      Ethanol is a liquid and water is also a liquid. The solvent is water (liquid), so this is also a liquid solution.

    Therefore, both are liquid solutions.
