The correct answer is option 1. 4.
The correct match is A-V, B-III, C-IV, D-II, E-I
| Column I |
Column II |
| (A) Soda Water |
(v) A solution of gas in liquid |
| (B) Sugar solution |
(iii) A solution of solid in liquid |
| (C) German silver |
(iv) A solution of solid in solid |
| (D) Air |
(ii) A solution of gas in gas |
| (E) Hydrogen gas in palladium |
(i) A solution of gas in solid |
(A) Soda Water: Soda water is a carbonated beverage that contains dissolved carbon dioxide gas in water. It can be classified as a solution of gas in a liquid (iii).
(B) Sugar solution: A sugar solution is formed when sugar (a solid) is dissolved in a liquid (such as water). Thus, it can be categorized as a solution of solid in a liquid (ii).
(C) German silver: German silver is an alloy made up of copper, nickel, and zinc. It is considered a solid solution because it consists of a homogeneous mixture of different metals in the solid state (iv).
(D) Air: Air is a mixture of various gases, primarily nitrogen, oxygen, carbon dioxide, and trace amounts of other gases. It can be classified as a solution of gases in gases (i).
(E) Hydrogen gas in palladium: Hydrogen gas can be absorbed by metals such as palladium, forming a solid solution. In this case, hydrogen gas is dissolved in palladium, making it a solution of gas in a solid (v). |
