Solve this:
Three students A, B, C prepared mixture using chalk powder, common salt and milk respectively in water. Whose mixture :
1) Would not leave the residue on filter paper after filtration ?
2) Would show tyndall effect ?
3) Would give transparent/clear solution ?

Dear Student,

1) Mixture done by B will not leave any residue as salt solution is a true solution.
2) Tyndall effect will be shown by milk solution of C. It's a colloidal solution. So it shows tyndall effect.
3) Salt solution will obviously be the clear solution. So, again its B.


Regards
