Question

In a solution, size of the particles was found to be 120 nm. Thus, (A) it is a type of true solution and scatters light (B) it is a type of colloidal sol and particle will be visible under ultramicroscope (C) it is a type of true solution and particle will not be visible even under ultramicroscope (D) it is a type of suspension and particles will be visible by naked eye

Size Less than 1 nm-true solution and invisible even under ultra-microscope. Between 1 nm and 100 nm-visible under ultramicroscope. More than 100 nm - visible even by naked eye. Thus, given solution with particle size 120 nm is a type of suspension.

Q. In a solution, size of the particles was found to be $120 nm$ . Thus,

it is a type of true solution and scatters light

it is a type of colloidal sol and particle will be visible under ultramicroscope

it is a type of true solution and particle will not be visible even under ultramicroscope

it is a type of suspension and particles will be visible by naked eye

Size Less than $1 nm$ -true solution and invisible even under ultra-microscope.

Between $1 nm$ and $100 nm$ -visible under ultramicroscope.

More than $100 nm$ - visible even by naked eye.

Thus, given solution with particle size $120 nm$ is a type of suspension.
