Solubility Curves and Their Interpretation starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Solubility Curves and Their Interpretation.
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.

A solubility curve shows that 60 g of a salt dissolves in 100 g of water at 70°C. If a solution at 70°C contains 80 g of the salt in 100 g of water, what will likely happen if the solution is disturbed?
A solubility curve shows that at 50°C, 90 g of a salt can dissolve in 100 g of water. If a solution at 50°C contains 90 g of the salt in 100 g of water, what is the solution's status?
A solubility curve shows that the solubility of a salt at 30°C is 50 g per 100 g water. If 60 g of the salt is added to 100 g of water at 30°C and all dissolves, what type of solution is this?
A solution contains 30 g of NaNO3 in 100 g of water at 20°C. The solubility of NaNO3 at 20°C is 85 g per 100 g water. Is the solution saturated, unsaturated, or supersaturated?

Which of the following best describes a saturated solution?
(1) Contains more solute than can dissolve
(2) Contains less solute than can dissolve
(3) Contains the maximum amount of solute that can dissolve at a given temperature
(4) Contains no solute
Which of the following best explains why the solubility of gases decreases with increasing temperature?
(1) Gas molecules escape more easily at higher temperatures
(2) Gas molecules dissolve more at higher temperatures
(3) The solvent becomes denser
(4) The gas reacts with the solvent
Which of the following is most likely to be true for a solubility curve of a salt that shows a steep increase with temperature?
(1) The salt is highly soluble at all temperatures
(2) The salt's solubility is not affected by temperature
(3) The salt's solubility increases rapidly with temperature
(4) The salt is insoluble at all temperatures
Which of the following is NOT a possible reason for a solubility curve to plateau (become horizontal) at higher temperatures?
(1) The solute decomposes at high temperature
(2) The solvent evaporates
(3) The solute reaches its maximum solubility
(4) The solute is completely insoluble
