Question

The particle size of the solute in true solution is:

• A. 1 Å – 10 Å
• B. 10 Å – 100 Å
• C. 100 Å – 1000 Å
• D. More than 1000 Å

Hint:

True solutions have very fine particles, typically in the range of 1 Å to 10 Å, which do not scatter light or settle out.

Answer 1

The Correct Option is A

In the context of chemistry, a true solution is a homogeneous mixture where the solute particles are completely dissolved in the solvent. The size of these particles determines the category into which the solution falls. 

The particle size of the solute in a true solution typically falls within a specific range:

• 1 Å–10 Å (angstroms)

This size range of solute particles ensures they are completely dissolved in the solvent, making the mixture homogeneous at the molecular level. Therefore, the correct option is: 1 Å – 10 Å.
