Answer 2

The student was unable to see sugar particles because they are too small to be seen.

• Water + sugar solution.
• When sugar particles are continuously stirred in water, the particles get dissolved in water forming a solution.
• Thus, they disappear after some time.
• The solution of water and sugar is an example of a true solution.

What is the true solution?

• When the size of the solute is less than 1nm.
• They are transparent in appearance.
• Homogeneous in nature.
