Give reasons for the following observations:
Brownian movement provides stability to the colloidal solution.
What happens when a freshly prepared precipitate of Fe(OH)3 is shaken with a small amount of FeCl3 solution?
Out of BaCl2 and KCl, which one is more effective in causing coagulation of a negatively charged colloidal Sol? Give reason.
Out of MgCl2 and AlCl3, which one is more effective in causing coagulation of negatively charged sol and why?
