Answer:
(i) Colloidal solution scatters light. Beaker B, which has a colloidal solution, will do so.
(ii) Beaker B, having a colloidal solution, will have Brownian movement.
(iii) Sugar dissolves completely in water. Hence Beaker A has a true solution. Beaker B has a colloidal solution of starch in water.
(iv) Since sugar in water is a true solution, it is also a homogeneous solution.
(v) A true solution has particles of size 10
A
o
to 2000
A

. Hence Beaker A will have such particles.
