What happens when

A freshly prepared precipitate of Fe(OH)3 is shaken with a small amount of FeCl3 solution?

Answer

When freshly precipitated Fe(OH)3 is shaken with the little amount of dilute solution of FeCl3(electrolyte).
Peptization process (ions of the electrolyte are adsorbed by the precipitate particles) takes place by converting the Fe(OH)3 precipitate into a colloidal solution positively charged solution of Fe(OH)3.
