When NaCl solution is added to Fe (OH)3 colloidal solution then- (a) [Fe (OH3)] Fe3+ is formed (b) [Fe (OH3)] Cl- (c) [Fe (OH3)] Na+ is formed (d) Fe (OH)3 is coagulated |

Answer» Correct Answer is: (d) Fe (OH)3 is coagulated When NaCl solution is added to a Fe (OH)3 colloidal solution, coagulation takes place. - When salt is added to water, it dissociates into Na+ & Clions. - As particles of Fe(OH)3 solution are positively charged, they get coagulated in presence of negatively charged Clions |
