Beaker A has sugar mixed with water and Beaker B has starch dissolved in water.
i) Which solution will scatter light?
ii) In which beaker does the Brownian movement take place?
iii) Name the type of solution that beaker A and beaker B contain.
iv) Which of the two solutions is homogeneous?
v) Identify the beaker that has particles of size 10∘A to 2000∘A
(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 10oA to 2000oA. Hence Beaker A will have such particles.
