Select wrong statement:-

Answer»

If a very small amount of `AlCl_(3)` is added to gold sl, coagulation occurs, but if a large quantity of `AlCl_(3)` is added, there is no coagulation
Organic ions are more strongly adsorbed on charged surfaces in comparison to INORGANIC ions
Both emulsifier and peptising agents stabilise colloids but their ACTIONS are different
Colloidal solutions are thermodynamically stable

Solution :When excess of an electrolyte is added, the colloidal PARTICLES are precipitated. This is because colloidal particles take up ions carrying CHARGE opposite to that present on themselves. This causes neutralization leading to their coagulation.
