What is the charge of gold sol? How do the particles acquire this charge?

The presence of electrical charge on colloidal particles is responsible for the stability of colloidal systems. Addition of AgNO_3 solution to KI solution results in a colloidal solution. What charge is likely to develop on the particles of'this colloidal solution ?

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

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 figure shows tracks of three charged particles in a uniform electrostatic fiels. Give the signs of threes charges. Which particle has the highest charge to mass ratio? '(##VPU_HSS_PHY_XII_CO1_E02_014_Q01##)'

What is an equipotential surface? What is the shape of equipotential surfaces for a given point charge?

The price of a gold sovereign(8 grams) is 22500 rupees. For jewellery, manufacturing charge is 6 % of the price of gold. A shop offers 20 % discount on this charge. How much money is needed to buy a bangle of one sovereign from here?

A charged particle is released from rest in a re gion of steady and uniform electric and magnetic fields, which are parallel to each other. What will be the nature of the path followed by the charged particle? Explain your answer.
