Sample questions
-
1.What is the common observation and the products formed when acids react with carbonates and bicarbonates? Also, select the correct chemical equations for the reaction of calcium carbonate and calcium bicarbonate with hydrochloric acid.
- A.Liberation of hydrogen gas; CaCO₃ + HCl → CaCl₂ + H₂O + H₂↑ and Ca(HCO₃)₂ + HCl → CaCl₂ + H₂O + H₂↑
- B.Liberation of carbon dioxide gas; CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂↑ and Ca(HCO₃)₂ + 2HCl → CaCl₂ + 2H₂O + 2CO₂↑
- C.Formation of a precipitate; CaCO₃ + HCl → CaCl₂ + CO₂ + H₂ and Ca(HCO₃)₂ + HCl → Ca(OH)₂ + CO₂
- D.Liberation of oxygen gas; CaCO₃ + 2HCl → CaO + H₂O + CO₂ and Ca(HCO₃)₂ + HCl → CaCl₂ + H₂O + O₂↑

2.Vinegar contains …………… acid.
- A.Phenol
- B.Hydrochloric
- C.Sulphuric
- D.Acetic
-
3.Match the following bases with their uses:
Base 1. Sodium hydroxide 2. Calcium hydroxide 3. Ammonium hydroxide 4. Magnesium hydroxide Use A. Antacid B. Manufacture of soap C. Whitewashing D. Laboratory reagent -
4.Which of the following hydroxides is not an alkali
- A.Ammonium hydroxide
- B.Calcium hydroxide
- C.Copper hydroxide
- D.Sodium hydroxide
-
5.What are basic salts, and why do they form? Select the correct description along with the appropriate chemical equations for the reaction of lead hydroxide, copper hydroxide, and magnesium hydroxide with hydrochloric acid and nitric acid.
- A.Basic salts form when the acidity of the base exceeds the basicity of the acid, containing a metallic cation, hydroxyl ion, and acid anion. Examples: Pb(OH)₂ + HCl → Pb(OH)Cl + H₂O; Cu(OH)₂ + HNO₃ → Cu(OH)NO₃ + H₂O.
- B.Basic salts are neutral compounds formed by complete neutralization of acids and bases. Examples: Pb(OH)₂ + 2HCl → PbCl₂ + 2H₂O; Cu(OH)₂ + 2HNO₃ → Cu(NO₃)₂ + 2H₂O.
- C.Basic salts result from the reaction of strong acids with weak bases, producing salts without hydroxyl ions. Examples: Mg(OH)₂ + HCl → MgCl₂ + H₂O; Pb(OH)₂ + HNO₃ → Pb(NO₃)₂ + H₂O.
- D.Basic salts form when acids react with metals, releasing hydrogen gas. Examples: Mg + 2HCl → MgCl₂ + H₂; Cu + HNO₃ → Cu(NO₃)₂ + H₂.
