Question

Which of the following will show tyndal effect
Salt solution
Sugar solution
Soap solution
Copper sulphate solution

Answer 1

Answer:

Explanation:true solutions do not show tyndall effect hence

           soap solution i.e a colloidal solution will show tyndall effect

Answer 2

Answer:

soap solution

Explanation:

Solution of soap in water will show Tyndall effect as the particles of soap are large enough to scatter light and hence form a colloidal solution. 

Whereas, salt in water is a homogenous solution, hence the particles are quite small and hence will not scatter light.
