Question

What happens when the newly formed Fe (OH) 3 is shaken with a small amount of Fecl3 solution?​

Answer 1

Answer:

When a freshly prepared precipitate of $Fe(OH)_{3}$ is shaken with a small amount of $FeCl_{3}$ solution, collodial dispersion of $Fe(OH)_{3}$ is formed. The process is called peptization. During peptization, a precipitate is converted into colloidal particles by adding suitable electrolyte. In the above example, $FeCl_{3}$ solution is peptizing agent.

Answer 2

Answer:

When a freshly prepared precipitate of Fe(OH)3 is shaken with a small amount of FeCl3 solution, collodial dispersion of Fe(OH)3 is formed. The process is called peptization. During peptization, a precipitate is converted into colloidal particles by adding suitable electrolyte.

OR

When freshly precipitated Fe(OH)3 is shaken with 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 colloidal solution positively charged solution of Fe(OH)3.
