Multiple Choice Questions
(a) a polar solvent dissolves a polar solute
(b) hydrogen gas is adsorbed (absorbed) by palladium
(c) a non-polar solvent dissolves a non-polar solute
(d) carbon dioxide gas is absorbed by caustic soda solution
Show Answer & Explanation
Answer: (b) hydrogen gas is adsorbed (absorbed) by palladium
Explanation:
1. Occlusion is the absorption of a gas by a metal; palladium occludes hydrogen about 900 times its own volume.
Teacher's Note:
1. Occlusion is a physical absorption of gases in solids.
2. Palladium is used to purify hydrogen for this reason.
(a) a little more solvent is added
(b) the temperature is raised
(c) the solution is stirred
(d) the solution is cooled
Show Answer & Explanation
Answer: (d) the solution is cooled
Explanation:
1. For most solids solubility falls on cooling, so the solution becomes supersaturated and crystals separate.
Teacher's Note:
1. Crystallisation is the method of purifying solids by cooling a hot saturated solution.
2. Adding solvent would make the solution unsaturated.
(a) Boyle temperature
(b) inversion temperature
(c) transition temperature
(d) critical temperature
Show Answer & Explanation
Answer: (c) transition temperature
Explanation:
1. The solubility of Na₂SO₄·10H₂O rises up to 32.4°C, where the hydrate changes into anhydrous sodium sulphate and the solubility then falls; this is the transition temperature.
Teacher's Note:
1. The break in the solubility curve marks a change of hydrate.
2. Transition temperature of Glauber's salt is 32.4°C.
(a) 1
(b) 0.5
(c) 1.25
(d) 1.5
Show Answer & Explanation
Answer: (d) 1.5
Explanation:
1. Concentration = 60 g per litre. Molar mass of NaOH = 40 g/mol, so molarity = 60/40 = 1.5 M.
Teacher's Note:
1. Molarity is moles of solute per litre of solution.
2. Convert the percentage to grams per litre first.
(a) 1
(b) 18
(c) 55.6
(d) 100
Show Answer & Explanation
Answer: (c) 55.6
Explanation:
1. 1 litre of water has a mass of 1000 g, which is 1000/18 = 55.6 mol, so its molarity is 55.6 M.
Teacher's Note:
1. Molar mass of water = 18 g/mol.
2. Density of water is 1 g/mL.
(a) molar solution
(b) molal solution
(c) normal solution
(d) saturated solution
Show Answer & Explanation
Answer: (a) molar solution
Explanation:
1. Molarity is the number of moles per litre of solution, so 1 mole in 1 litre is a 1 M (molar) solution.
Teacher's Note:
1. Molality uses 1 kg of solvent instead.
2. Molarity depends on temperature through the volume of solution.
(a) 1.0 m
(b) 0.1 m
(c) 0.12 m
(d) 12 m
Show Answer & Explanation
Answer: (a) 1.0 m
Explanation:
1. Molar mass of MgSO₄ = 120 g/mol, so 12 g = 0.1 mol. Molality = 0.1 mol / 0.1 kg of water = 1.0 m.
Teacher's Note:
1. Molality is moles per kilogram of solvent.
2. Convert 100 g of water to 0.1 kg.
(a) may increase with decrease in temperature
(b) always increases with temperature
(c) is independent of temperature
(d) increases only with pressure
Show Answer & Explanation
Answer: (a) may increase with decrease in temperature
Explanation:
1. Lime water dissolves more calcium hydroxide in cold water than in hot water: its solubility falls as temperature rises.
Teacher's Note:
1. Most solids are more soluble in hot water; calcium hydroxide is an exception.
2. Gases also become less soluble when heated.
