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 10
A solution contains 15 g of solute in 100 g of water at 40°C. If the solubility of the solute at 40°C is 20 g per 100 g of water, is the solution saturated, unsaturated, or supersaturated?
A student adds sugar to water until no more dissolves and some remains at the bottom. What type of solution is this?
Define a supersaturated solution.
Describe the effect of particle size on the rate of dissolution of a solute.
Explain how pressure affects the solubility of gases in liquids.
Explain why polar solutes tend to dissolve in polar solvents.
A solution at 25°C can dissolve a maximum of 36 g of salt in 100 g of water. If 40 g of salt is added to 100 g of water at this temperature, what type of solution is formed? (1) Unsaturated (2) Saturated (3) Supersaturated (4) Dilute
A solution contains 15 g of solute in 100 g of water at 40°C. If the solubility of the solute at 40°C is 20 g per 100 g of water, is the solution saturated, unsaturated, or supersaturated?
A solution is prepared by dissolving 5 g of a solute in 95 g of water. If the solubility of the solute at this temperature is 10 g per 100 g of water, is the solution saturated?

The phrase 'like dissolves like' refers to which property of solubility? (1) Temperature dependence (2) Nature of solute and solvent (3) Pressure dependence (4) Particle size
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
If a solution contains less solute than it can hold at a given temperature, it is called a(n) _______ solution.
The solubility of a gas in a liquid generally _______ as the temperature increases.
A solution is prepared by dissolving 5 g of a solute in 95 g of water. If the solubility of the solute at this temperature is 10 g per 100 g of water, is the solution saturated?
True or False: All saturated solutions are also supersaturated.
True or False: Increasing the temperature always increases the solubility of a solid in a liquid.
True or False: The solubility of a gas in a liquid is higher at lower temperatures.
