Select from the dropdown list to complete the text.

( SATURATION CONCENTRATION, UNSATURATED SOLUTION, SUPERSATURATED SOLUTION, SATURATED SOLUTION ) is the extent of Solubility

Explanation

Question 11 of 20

1

Factors affecting solubility:

Select one or more of the following:

Nature of Solute and Solvent
Temperature
Pressure
Stirring/Agitiation
Size of Solute (Surface Area)

Explanation

Question 12 of 20

1

Nature of Solute and Solvent:
Nonpolar Solvents dissolve Polar & Ionic Solutes

Select one of the following:

True
False

Explanation

Question 13 of 20

1

Temperature:
Gasses occupy more space when temperature is increades making it harder to mix w/ the solvent

Select one of the following:

True
False

Explanation

Question 14 of 20

1

Fill the blank space to complete the text.

Pressure:
Law states that solubility of a gas increases with partial pressure of the gas above the liquid
>> pressure makes the solvent dissolve the compressed solute easier
