Answer :

(i) Soda water- (e) A solution of the gas in liquid


Explanation: Carbonated drinks are a system of gas in a liquid. The solubility of CO2 in water is increased by applying high pressure. This is also known as Henry’s law. Henry’s law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the surface of liquid or solution.


(ii) Sugar solution – (c) A solution of solid in liquid


Explanation:Sugar crystals(solute) are solids dissolved in a liquid(solvent). Therefore, it is a solution of solid in a liquid.


(iii) German silver – (d) A solution of solid in solid


Explanation:German silver is an alloy of nickel, zinc and copper. Alloys are amalgamations of two or more solids. Therefore, it is a solution of solid in solid.


(iv) Air – (b) A solution of the gas in gas


Explanation: Air is a homogenous mixture of different gases. Different gases mix together uniformly, and therefore it is a solution of the gas in gas.


(v) Hydrogen gas in palladium- (a) A solution of the gas in solid


Explanation:Hydrogen(a gas) gets adsorbed onto the surface of palladium( a solid metal). Therefore, it is a solution of the gas in solid.
