Solutbility

Question 1

Water’s physical properties

Answer 1

Colourless liquid
Melting point 0 degrees
Boiling point 100 degrees
Used as a solvent in drink and washing

Question 2

List the factors affecting rate of dissolving

Answer 2

Temperature
Stirring
Volume of solvent

Question 3

Solubility meaning

Answer 3

It is the mass of a solid that will saturate 100g of water (or solvent) at a particular temperature. Units = g/100g water

Question 4

Saturated solution meaning

Answer 4

It is one in which no more solid will dissolve at a particular temperature.

Question 5

How to find the solubility of a substance?

Answer 5

Mass of solute divided by mass of solvent X 100

Question 6

Explain the effect of temperature on the solubility of solids and gases

Answer 6

As the temperature rises the solubility of solids goes up and the solubility of gases goes down
