Question

if the solute particle size is smaller than …… then it cannot seen by naked eyes. (1 Point)
1 cm
1 nm
1m
1 mm​

Answer 1

Answer:

smaller than 1nm

Explanation:

The particles of a solution are smaller than 1 nm (10-9 metre) in diameter. So, they cannot be seen by naked eyes. Because of very small particle size, they do not scatter a beam of light passing through the solution. So, the path of light is not visible in a solution

Answer 2

If the solute particle size is smaller than 1 nm then it cannot seen by naked eyes. (Option b)

• The particles of a solution is seen to be homogeneous in nature.
• When a beam of light is passed through this homogeneous mixture, they are unable of scatter a beam of light that is passed through them.
• This is because of the size of the particles within the solution are small.

• As a result, the light is invisible and the particles are not visible for the naked eyes.
• Hence, the option two is the correct answer.
