The existence of charge on colloidal particles is confirmed by electrophoresis experiment. In the coagulation of,a negative sol, the coagulating power is in the order `AI^(3+) > Ba(2+) > Na^+`. Name and state the rule behind this?

The existence of charge on colloidal particles is confirmed by electrophoresis experiment.What is meant by electrophoresis ?

In the coagulation of a positive sol, the flocculating power of the ions PO_(4)^(3-), SO_(4)^(2-) and Cl^(-) decreases in the order

The Ion which is more effective for the coagulation of negative sol As_2S_3 is ?

Among the anions Cl^(-),SO_(4)^(-2),PO_(4)^(-3) , the coagulating power follows the order

Assertion: In the coagulation of a negative sol the flocculationg power is in the order: Al^(3+)gtBa^(2+)gtNa^(+) Reason: Greater the valence of the flocculating ion added, greater is its power to cause precipitation.

The coagulating powers of electrolytes having ions Na^(+), Al^(3+) and Ba^(2+) for arsenic sulphides sol increases in the order

Which of the following electrolytes is most effective for the coagulation of Fe(OH)_3 sol and why? NaCl, Na_2 SO_4, Na_3 PO_4

As_2S_3 sol particles are -negatively charged.What happens when barium chloride solution is added to the above sol?

Select the correct statements. : Zeta potential is the potential needed for electrophoresis, During electrophoresis, colloidal particle in A s 2 S 3 solution move towards anode, During electroosmosis, dispersed phase move towards oppositely charged electrode on application of electric field, Tyndall effect can be shown by true solution
