Electric current is passed through a colloidal solution. D.P.particles move towards anode.The anode may be called:

When electric current is passed through an ionic hydride in molten state:

When electric current is passed through an ionic hydride in molten state:

Explain what is observed when (i) KCl, an electrolyte, is added to hydrated ferric oxide sol, (ii) an electric current is passed through a colloidal solution, (iii) a beam of lights is passed through a colloidal solution.

Assertion : On passing electric current in colloidal solution they do not move towards anode or cathode. Reason: They do not contain any charge

Explain the following observation: a. A beam of light passing through a colloidal solution has a visible path. Passing an electric currenet through a colloidal solution removes colloidal particles from it. c. Ferric hydroxide sol coagulates on addition of potassium sulphate.

When a strong beam of light is passed through a colloidal solution, the light will:

The electric current passes through a metallic wire produces heat because of :

When an electric current is passed through a cell having an electrolyte, then the cations and anions move to their respective electrodes if the cathode is pulled out of the solution then

When electric current is passed through water, it undergoes a …………….. Reaction.

Two platinum electrodes were immersed in a solution of CuSO_(4) and electric current was passed through the solution. After some time, it was found that colour of CuSO_(4) disappeared with evolution of gas at the electrode. The colourless solution contains.
