Q 9. Which of the following will show “Tyndall effect”?
(a) Salt solution
(c) Copper sulphate solution
(d) Starch solution.
Tyndall effect is shown by the colloidal solution and suspension and it is not shown by true solution.
Therefore, in the above given solution only milk and starch solution will be able to scatters the light and hence show tyndall effect.
