Solubility

Question 1

Solvent

Answer 1

The liquid in which the solute dissolves

Question 2

Solute

Answer 2

A soluble substance which dissolves

Question 3

Solution

Answer 3

A mixture of a solute dissolved in a solvent

Question 4

Insoluble

Answer 4

A substance that will not dissolve in a particular solvent

Question 5

Factors affecting rate of dissolving

Answer 5

1. Temperature
2. Stirring
3. Volume of solvent
4. Mass of solute
5. Surface area of the solute (granules, powder or cubes)

Question 6

Solubility

Answer 6

The mass of a solid that will saturate 100g of water at a particular temperature
Units of solubility: Xg/per 100g water/H2O

Question 7

Saturated solution

Answer 7

A solution in which no more solid will disolve at a particular temperature.

Question 8

How to calculate solubility

Answer 8

Mass of solute
———————- X 100
mass of solvent

Question 9

How does the solubility of gas change with temperature

Answer 9

As temperature rises solubility lowers unlike other non-gas solutes
