Question

Assertion: Two components of the binary solution are solute and solvent.

Reason:​ Particle size in true solution lies between $1$nm to $100$ nm.​

• A. If ‘A’ and ‘R’ are true and ‘R’ is the correct reason for ‘A’.
• B. If ‘A’ and ‘R’ are true and ‘R’ is not the correct reason for ‘A’.
• C. If ‘A’ is correct and ‘R’ is wrong.
• D. If ‘A’ is wrong and ‘R’ is correct.

Answer 1

The correct option is C

If ‘A’ is correct and ‘R’ is wrong.

Answer:

The explanation for the Assertion statement:

Solution:

• Solutions are a homogeneous mixture of solute and solvent.
• It is a homogeneous mixture of two or more two components.
• For example, A solution of salt in water in which salt is solute and water is solvent.
• Solution = Solute + Solvent

Solvent:

• A substance that can dissolve a given solute and form a solution with it is known as a solvent.
• For example, water, and ethanol.

Solute:

• A solute is a substance that presents in less amount and dissolves in the solvent to make a solution.
• For example In salt solution, salt is the solute.

The explanation for the Reason statement:

True solution:

A true solution is a homogeneous mixture that has uniform composition and properties throughout the solution.

The size of particles of the true solution is smaller than a $1$nanometre.

Conclusion:

So, ‘A’ is correct and ‘R’ is wrong.

Therefore, option C is the correct answer.
