A) adsorption of hydroxyl ion
B) adsorption of hydrogen ion
C) adsorption of ferric ion
D) absorption of ferric ion
Correct Answer: C
Solution :
\[\text{Fe(OH}{{\text{)}}_{\text{3}}}\]sol carries charge because of the adsorption of ferric ions as \[Fe{{(OH)}_{3}}+FeC{{l}_{3}}\xrightarrow{{}}\underset{\text{sol}\,\text{of}\,\text{ferric}\,\text{hydroxide}}{\mathop{Fe{{(OH)}_{3}}:F{{e}^{3+}}}}\,\]\[+\,3C{{l}^{-}}\]You need to login to perform this action.
