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 11

A solution contains 40 g of sugar in 200 g of water at 20°C. If the solubility of sugar at this temperature is 200 g per 100 g water, is the solution saturated, unsaturated, or supersaturated?

A student adds 10 g of salt to 100 g of water at 25°C and all the salt dissolves. The student then adds another 30 g of salt, but only 20 g dissolves. What is the solubility of salt in water at 25°C based on this experiment?

Describe the effect of temperature on the solubility of most salts in water.

Describe what happens when a saturated solution is cooled.

Explain how pressure affects the solubility of gases in liquids.

Explain why carbonated beverages lose their fizz faster at higher temperatures.

Explain why increasing the surface area of a solute increases its rate of dissolution.

Explain why sugar dissolves more quickly in hot tea than in cold tea.

If 36 g of NaCl dissolves in 100 g of water at 25°C, what is the solubility of NaCl at this temperature?

State Henry's Law in your own words.

The solubility of KNO₃ in water at 60°C is 110 g per 100 g water. If 150 g of KNO₃ is added to 100 g of water at 60°C, how much will remain undissolved?
