Question

1)light scattering in colloidal particles is visible with the help of naked eye -true/false
2)Do suspensions scatter light through tyndall effect?
3)how can we seperate salt from sugar?
4)how can we seperate sugar from salt?

Answer 1

1)These particles can scatter light. A phenomenon known as Tyndall effect.Hence statement is true.

2)Tyndall effect is the phenomenon of scattering of light by the particles of colloid or suspension because of which the path of light is illuminated.
So yes.

3)Sugar is soluble in alcohols while salt is not. Simply mix the two in alcohol and filter the solution to get thesalt. Then evaporate the alcohol sugar mixture and you will be left with the sugar. Done.

4) The above method lets you seperate out both hence can be used as answer for this question as well.

Hope this helps:)
