A mixture of sulphur and carbon disulphide is (a) heterogeneous and shows Tyndall effect (b) homogeneous and shows Tyndall effect

If all the reactants and products present in an equilibrium mixture are in same  phase → homogeneous equilibrium.  Example: N2(g) + 3H2(g)  ⇌ 2NH3(g) If all the reactants and products present in an...

A homogeneous mixture is a mixture having a uniform composition throughout the mixture. For example, mixtures of salt in water, sugar in water, copper sulphate in water, iodine in alcohol,...

A homogeneous mixture is a mixture having a uniform composition throughout the mixture. For example: salt in water, sugar in water, copper sulphate in water A heterogeneous mixture is a...

Homogeneous mixture - soda water, air, vinegar, filtered tea.  Heterogeneous mixture - wood, soil.

(b) and (d) are colloids and will show Tyndall Effect.

Homogeneous— mixture of salts and water only  Heterogeneous— contains salts, water, mud, decayed plant etc.

Hint—Tyndall effect can be seen when light passes through a heterogeneous mixture. Example, when sunlight passes through the canopy of a dense forest.

[Hint : (a) The size of dispersed phase particles is not much smaller the wavelength of light used. (b) The refractive indices of the dispersed phase and the dispersion medium differ...

(i) Electrophoresis: The movement of colloidal particles under the influence of an applied electric field is known as electrophoresis. Positively charged particles move to the cathode, while negatively charged particles move...

(C) carbon dioxide only
