Answer:
Assertion (A): The particles of a solution are smaller than 1 nm (10-9 metre) in diameter
Reason (R): Solution can scatter a beam of light passing through it
Explanation:
The particles of a solution are smaller than 1 nm (10-9 metre) in diameter. ... 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. The solute particles cannot be separated from the mixture by the process of filtration.
The particles of size less than 1 nm cant scatter light .
Explanation:
Tyndall effect
The scattering of light by solution due to which path of light becomes visible.
It is shown by solution with particle size between 1nm to 100nm .
That is the colloidal range particles .
It is not shown by true solutions or suspensions as true solution have very small size particles (less than 1nm) and suspension has very big size particles (more than 100nm ).
The process of scattering of light is shown in figure .
