Question

What is a true solution?

• A. Sugar solution
• B. Blood
• C. Starch
• D. Ink

Answer 1

The correct option is A

Sugar solution

Explanation for Correct option:

A. Sugar solution:

True Solution

• "A true solution is a homogeneous mixture of two or more components dissolved in a solvent with a particle size of less than ${10}^{-9}\mathrm{m}$ m or $1\mathrm{nm}$. "
• A simple sugar solution in water is an example of a true solution.
• Filter paper, which is likewise invisible to the human eye, cannot separate particles from true solutions.

Properties of True solution:

• A true solution is a homogenous mixing of solute and solvent.
• In a true solution, filtration cannot separate the solute from the solution.
• The particle size of the solute is similar to that of the solvent, and the solvent and solute pass through the filter paper simultaneously.

Out of all the options given only option, Sugar solution satisfies all properties of the True solution.

Explanation for incorrect options:

While considering the other options like blood, Starch and Ink are termed as colloidal solution and they are not satisfying the properties of a true solution.

Thus, options B, C, and D are incorrect.

Hence, the correct option is A i.e. Sugar solution.
