How to use table G

The ability of a Solute to dissolve in a Solvent

​

Solubility

Title: Solubility Curves at Standard Pressure

​

Table G -
Reference Tables

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

​

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

​

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

Can you find the Solubility Curve for KNO₃ on Table G?

Reference Tables

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.

Solubility is refered to in three terms

• Unsaturated

• Saturated and

• Supersaturated

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
