Solubility and Factors Affecting Solubility
Chemistry ⇒ Solutions and Colloids
Solubility and Factors Affecting Solubility starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Solubility and Factors Affecting Solubility.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A carbonated drink is bottled under high pressure. What happens to the solubility of carbon dioxide gas when the bottle is opened?
A solution contains 12 g of solute in 100 g of water at 25°C. If the solubility of the solute at 25°C is 15 g per 100 g of water, is the solution saturated, unsaturated, or supersaturated?
A student adds 5 g of salt to 100 g of water and all the salt dissolves. She then adds another 10 g and it also dissolves. She adds 10 g more and some salt remains undissolved. What is the solubility of salt in water under these conditions?
A student dissolves 10 g of sugar in 100 g of water at 20°C. She then heats the solution to 40°C and finds she can dissolve 20 g more. What factor has changed the solubility?
A carbonated drink is bottled under high pressure. What happens to the solubility of carbon dioxide gas when the bottle is opened?
A solution at 25°C can dissolve 36 g of salt in 100 g of water. If you add 40 g of salt to 100 g of water at 25°C, what type of solution is formed? (1) Unsaturated (2) Saturated (3) Supersaturated (4) Dilute

Which factor does NOT affect the solubility of a solid in a liquid? (1) Temperature (2) Pressure (3) Nature of solute and solvent (4) Surface area of solute
Which of the following best defines solubility? (1) The amount of solute that can dissolve in a given amount of solvent at a specific temperature (2) The ability of a solvent to evaporate (3) The amount of solvent that can dissolve in a solute (4) The temperature at which a solution boils
Which of the following best describes a supersaturated solution? (1) Contains less solute than it can hold (2) Contains more solute than it can normally hold (3) Contains only solvent (4) Contains undissolved solute at the bottom
Fill in the blank: The maximum amount of solute that can dissolve in a solvent at a given temperature is called its _______.
Fill in the blank: The solubility of a substance is usually given as grams of solute per _______ grams of solvent at a specific temperature.
Fill in the blank: The solubility of most gases in water _______ as the temperature increases.
The phrase 'like dissolves like' refers to the fact that _______ solutes dissolve best in _______ solvents.
True or False: A solution in which more solute can be dissolved at a given temperature is called unsaturated.
True or False: All ionic compounds are soluble in water.
True or False: Increasing the temperature always increases the solubility of a solid in a liquid.
True or False: Pressure has little effect on the solubility of solids and liquids, but greatly affects the solubility of gases.
