(A – p, q) ; (B–r) ; (C – q, t) ; (D – s) ; (E – u)
Sol. Gold sol is prepared by Bredig's Arc method and it is negatively charged
Purification of colloidal solution is done by dialysis.
As 2 S 3 sol is prepared by Double decomposition reaction and it is negatively charged.
Zeta potential-potential difference between stable layer and disperse layer. (Electro kinetic potential)
(e) Casein is lyophilic Protective colloid.
