Which one amongst the following will show Tyndall effect?
(i) Common salt solution
(ii) Copper sulphate solution
iii) Milk will show Tyndall effect as milk is a colloid.
Common salt solution and copper sulphate solution does not show Tyndall effect as they are less than 1nm in diameter and cannot be seen by naked eye. Due to its small particle size, they do not scatter a beam of light passing through the solution.
