Zeta potential (or electrokinetic potential) is the

potential difference between fixed charged layer and the diffused layer having opposite charge

potential required to bring about coagulation of a colloidal sol

potential required to give the particles a speed of 1 cm/s in the sol

potential difference between fixed charged layer and the diffused layer having opposite charge

potential energy of the colloidal particles.

A colloidal solution is subjected to an electrical field. The particles move towards anode. The coagulation of same sol is studied using NaCl,$BaCl_2$ and $AlCl_3$ solutions. Their coagulating power should be

$ AlCl_3$ > $BaCl_2$ > NaCl

$BaCl _2$ > $AlCl_3$ > $NaCl $

$ AlCl_3$ > $BaCl_2$ > NaCl

potential difference between fixed charged layer and the diffused layer having opposite charge

$ AlCl_3$ > $BaCl_2$ > NaCl

Elastic gels when placed in contact with water, they absorb water and swell. This property is called
