Sample questions
-
1.What happens when alkalies are warmed with ammonium salts, and which of the following represents the balanced equation for the reaction of ammonium chloride with sodium hydroxide?
- A.Ammonia gas is liberated; NH₄Cl + NaOH → NaCl + H₂O + NH₃↑
- B.Hydrogen gas is released; NH₄Cl + NaOH → NaCl + H₂ + NH₃
- C.No reaction occurs; NH₄Cl remains unchanged with NaOH
- D.Chlorine gas is produced; NH₄Cl + NaOH → NaOH + Cl₂ + NH₃
-
2.Match the following types of reactions with their examples: (i) Combination (ii) Synthesis (iii) Displacement (iv) Decomposition
-
3.The equation between an acid and a base is XOH + HY → XY + H₂O In the given equation, which specie act as a cation?
- A.Y
- B.OH
- C.H
- D.X
-
4.A chemical reaction between hydronium ions of an acid and OH ions of a base to form unionised water is called ...
- A.Formation
- B.Galvanisation
- C.Alkalisation
- D.Neutralisation
-
5.Which of the following correctly describes the method of preparing insoluble salts by direct combination and provides a valid example?
- A.Insoluble salts are prepared by combining a metal and a non-metal through heating, e.g., Pb + S → PbS.
- B.Insoluble salts are formed by neutralizing an acid with a base, e.g., NaOH + HCl → NaCl + H₂O.
- C.Insoluble salts are obtained by reacting two soluble salts, e.g., AgNO₃ + NaCl → AgCl + NaNO₃.
- D.Insoluble salts are prepared by dissolving a metal oxide in water, e.g., CaO + H₂O → Ca(OH)₂.
