Factors affecting Solubility

Why do crushed substances dissolve faster than whole ones?

• Crushed substances have a greater surface area exposed to the solvent, allowing for quicker dissolution.

• Whole substances have a higher temperature, which speeds up dissolution.

• Crushed substances are lighter, making them easier to mix with the solvent.

• Whole substances contain more impurities, which slow down the dissolution process.

What is the effect of particle size on solubility?

• Smaller particles dissolve faster due to a larger surface area.

• Larger particles dissolve faster due to a larger surface area.

• Particle size has no effect on solubility.

• Smaller particles dissolve slower than larger particles.

Why do sugar particles dissolve faster in hot water?

• In hot water, water particles move faster, increasing the interaction with sugar particles and promoting faster dissolution.

• Cold water has a higher concentration of sugar particles, which helps in faster dissolution.

• Hot water contains more sugar molecules, which aids in the dissolution process.

• The temperature of hot water causes sugar to break down into smaller particles more quickly.

What factors affect solubility?

• Temperature, particle size, and rate of stirring.

• pH level, pressure, and color of the solute.

• Molecular weight, boiling point, and density.

• Concentration, volume, and surface area.

What is an unsaturated solution?

• An unsaturated solution is one that can still dissolve more solute at a given temperature and pressure.

• An unsaturated solution is one that has reached its maximum solute capacity.

• An unsaturated solution is one that contains no solute at all.

• An unsaturated solution is one that can only dissolve solute at high temperatures.

What happens to the solubility of gases when temperature increases?

• The solubility of gases typically increases as temperature increases.

• The solubility of gases typically decreases as temperature increases.

• The solubility of gases remains unchanged with temperature increases.

• The solubility of gases fluctuates randomly with temperature increases.

What is the importance of solubility in everyday life?

• It is only important in cooking.

• It plays a role in pharmaceuticals, cooking, and environmental science.

• It has no significant impact on daily activities.

• It is only relevant in industrial applications.

What is a saturated solution?

• A solution that contains more solute than it can hold at a given temperature and pressure.

• A solution in which no more solute can dissolve at a given temperature and pressure.

• A solution that has reached its boiling point and cannot dissolve any more solute.

• A solution that is completely solid and cannot dissolve any solute.

What is solubility?

• The ability of a substance to change its state.

• The ability of a substance to dissolve in a solvent, forming a solution.

• The measure of how much solute can be added to a solvent before saturation occurs.

• The process of separating a mixture into its components.

What is the relationship between solubility and molecular interactions?

• Solubility is influenced by the interactions between solute and solvent molecules, such as hydrogen bonding and polarity.

• Solubility is solely determined by temperature and pressure.

• Molecular interactions have no effect on solubility.

• Solubility is only affected by the size of the solute molecules.
