Sample questions
-
1.How would you distinguish between dilute hydrochloric acid (HCl) and dilute nitric acid (HNO₃) by adding only one solution?
- A.Add sodium hydroxide solution; HCl produces effervescence while HNO₃ does not.
- B.Add silver nitrate solution; HCl forms a white precipitate while HNO₃ does not.
- C.Add barium chloride solution; HCl forms a white precipitate while HNO₃ does not.
- D.Add copper turnings; HNO₃ produces a brown gas while HCl does not.
-
2.(XII) What is the balanced chemical equation for the reaction between hydrogen and chlorine?
- A.H₂ + Cl₂ → HCl
- B.H₂ + Cl₂ → 2HCl
- C.H₂ + 2Cl₂ → 2HCl
- D.2H₂ + Cl₂ → 2HCl
-
3.Which reagent can distinguish between magnesium chloride and magnesium nitrate solutions, and what observation confirms the presence of chloride ions?
- A.Sodium hydroxide; formation of a white precipitate.
- B.Silver nitrate; formation of a curdy white precipitate of AgCl.
- C.Barium chloride; formation of a white precipitate.
- D.Dilute sulphuric acid; evolution of a gas.
-
4.(XIII) Which of the following correctly represents the balanced chemical equation for the reaction between magnesium oxide and hydrochloric acid?
- A.MgO + HCl → MgCl + H₂O
- B.MgO + 2HCl → MgCl₂ + H₂O
- C.MgO + HCl → MgCl₂ + H₂
- D.2MgO + HCl → Mg₂Cl + H₂O
-
