Factors That Effect Solubility

What is Solubility

• the solvent particles are attacked by solute

• how well a solute dissolves in a given amount of solvent.

• the two substances are not evenly mixed throughout.

• how well a solvent dissolves in a given amount of solute.

Liquids at higher temperatures

• Have more solubility than liquids at lower temperatures.

• Have the same amount of solubility as liquids at lower temperatures.

• Have less solubility than liquids at lower temperatures.

• Dissolve solutes slower than liquids at lower temperature's

Which of the following would dissolve the fasted in water?

• powdered sugar ( most surface area)

• granulated sugar (moderate amount of surface area)

• broken sugar cubes (moderate amount of surface area)

• Sugar Cubes (least amount of surface area)

Answer explanation

Increases the surface area of the solute (crushing, grinding). Makes it easier for the solvent particles to surround the. More particles expose, more frequent collisions, the higher chance of successful solute- solvent collision).

5 grams of sugar would dissolve the fastest in

• cold water

• warm water

• hot water

• none of the above

Answer explanation

increasing the temperature increase the rate of solubility ( dissolve).

More gas dissolves in

• a cold Diet coke than a warm Diet Coke

• a warm Diet coke than a cold Diet coke

• a warm salt water solution than a cold salt water solution

• a lower pressure bottle of Diet coke than a higher pressure bottle of Diet Coke.

Answer explanation

gases will have a decrease in solubility in a liquid of increase temperatures

Which of the following would result in being able to dissolve a greater amount of solid in a solution?

• Lower the temperature.

• Decrease the pressure of the solution.

• Increase the pressure of the solution.

• Heat the solution.

Which of the following statements is true?

• An increase in temperature decreases the solubility of most solids, but increases the solubility of gases.

• An increase in temperature increases the solubility of most solids and gases.

• An increase in temperature decreases the solubility of most solids and gases.

• An increase in temperature increases the solubility of most solids, but decreases the solubility of gases.

A solution containing the maximum amount of solute for a given amount of solvent at a constant temperature and pressure

• Electrolyte

• Saturated Solution

• Solute

• Solvent

How does a solution become supersaturated?

• dissolve lots of solute in it.
• dissolve a little solute in it. 
• dissolve more solute than you should be able to. 
• dissolve a solvent in it. 

__________ are made up of solutes and solvents.

• Solutions
• Suspensions
• Heterogeneous Mixtures
• Pure Substances
