What to expect: This mock test covers key concepts from the Metallurgy chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.What is the role of the layer of cryolite and fluorspar sprinkled over the surface of the electrolytic mixture in the extraction of aluminium?
- A.It lowers the melting point of alumina, reducing energy consumption.
- B.It reduces heat loss by radiation and prevents the burning of the anode.
- C.It acts as a catalyst to speed up the electrolytic reaction.
- D.It neutralizes impurities in the electrolytic mixture to form slag.
-
2.What is the term for a substance prepared by adding other metals to a base metal in appropriate proportions to obtain certain desirable properties?
- A.Amalgam
- B.Alloy
- C.Compound
- D.Ore
-
3.From the list of characteristics given below, select the five which are relevant to non-metals and their compounds
- A.Ductile
- B.Conduct electricity
- C.Brittle
- D.Acidic oxides
- E.Basic oxides
- F.Discharged at anode
- G.Discharged at cathode
- H.Ionic chlorides
- I.Covalent chlorides
- J.Reaction with dilute sulphuric acid yields hydrogen
- K.1, 2 or 3 valence electrons
- L.5, 6, 7 valence electrons
-
4.Match the following: E. Column-I (i) Galvanization (ii) Bodies of aircrafts (iii) Surgical instruments (iv) Expands on cooling (v) Statues Column-II (a) Duralumin (b) Stainless steel (c) Type metal (d) Brass (e) Zinc
-
5.Describe the reaction of aluminium with air. Which of the following statements correctly summarizes this reaction?
- A.Aluminium reacts with air at room temperature to form a thick, porous layer of aluminium oxide that accelerates corrosion.
- B.At room temperature, aluminium forms a thin, tough layer of aluminium oxide that protects it from further corrosion, while at high temperatures, it burns to form aluminium oxide and nitride.
- C.Aluminium does not react with air at any temperature, remaining completely inert.
- D.When exposed to air, aluminium immediately forms aluminium hydroxide, which dissolves in water to corrode the metal.
