1.	What is observed when sodium chloride is added to a colloidal solution of ferric hydroxide?
Answer» When sodium chloride is added to ferric hydroxide solution gets coagulated. This is because `Cl^(ɵ)` ions from `NaCl` neutralize the `+ve` charge on `Fe(OH)_(3)` solution.When sodium chloride is added to ferric hydroxide solution gets coagulated.
