Question
(i) At 298 K the volume of NH3 adsorbed by 1g of charcoal is higher than that of H2 under similar conditions.
(ii) The movement of colloidal particles towards the oppositely charged electrodes on passing electric current is known as Brownian movement.
(ii) The movement of colloidal particles towards the oppositely charged electrodes on passing electric current is known as Brownian movement.
Options
A.T, T
B.T, F
C.F, T
D.F, F
Solution
(i) NH3 is easily liquifiable, so ordered more than H2.
(ii) This phenomenon is known as electrophoresis, not Brownian movement.
