Solubility

Title: Solubility Curves at Standard Pressure

​

Table G -
Reference Tables

Solubility is the amount of solute dissolve in a specific amount of solvent

​

Y Axis
SOLUBILITY
(g of solute/100g H2O)

Solubility is dependent on TEMPERATURE. Changing the temperature changes the amount od solute that will dissolve

​

X Axis
Temperature
( ^OC )

you used
2,4, 6 and 8 g /5g H20 on the y axis with temperature on the X Axisand got the followin g curve

Take a Coser Look At Table G

Most of the substances on this table are Solids.

Table G -
Reference Tables

Solids have a positive slope (lines that go up.) on a solubility Graph.

Table G -
Reference Tables

Particles move faster (have more kinetic energy) as temperature increases.
So, particles collide more often and dissolving happens faster.

HOT

COLD

Gases have a Negative slope (lines that go downwards) on a solubility Graph.

Table G -
Reference Tables

In a Hot environment gas particles are quick to escape the can.
In a colder environment gas particles move slowly and will stay in solution longer.

Multiple Choice

How is a supersaturated solution made?

• By making a saturated solution, heating it up and adding more solvent, then cooling the solution.

• By making a saturated solution, heating it up and adding more solute, then cooling the solution.

• By making a saturated solution and then heating it up.

• By making an unsaturated solution, then cooling it down.

Multiple Choice

Which of the following is NOT true regarding solubility curves?

• The solid line represents saturated solutions.

• The solubility of all substances increase with temperature

• Every substance has its own curve.

• Solubility is plotted against temperature.

Multiple Choice

How is solubility determined?

• By determining the mass of a solute in 100g of a solvent.

• By determining the maximum mass of a solute that can be dissolved in 100g of a solvent at a given

  temperature.

• By determining the maximum mass of a solute that can be dissolved in 100g of a solvent at any

  temperature.

• By determining the maximum mass of a solvent that can be dissolved in 100g of a solute at a given

  temperature.

Multiple Choice

Which of the following statements best describes a supersaturated solution?

• A solution that contains more than the maximum amount of dissolved solute than a saturated solution

  under the same conditions.

• A solution that contains the maximum amount of a dissolved solute under different conditions.

• A solution that contains less than the maximum amount of dissolved solute.

• A solution that contains the maximum amount of dissolved solute.

How to determine solubilty from a solubility curve

On the curve - solution is saturated

​
Under the curve - solution is unsaturated

Above the curve - Solution is supersaturated
