23
Q

Solution

A

The mixture that forms when a solute dissolves in a solvent

24
Q

Solvent

A

The liquid in which the solute dissolves

25
Q

Solute

A

The solid/liquid/gas that dissolves in a solvent to form a solution

26
Q

Saturated Solution

A

A solution containing the maximum amount of dissolved solute

27
Q

Solubility

A

The maximum massof solute in grams that dissolves in 100g of solvent

28
Q

What is the effect of impurities on melting and boiling point?

A

Impurities lowers the melting point and increase the boiling point.

29
Q

How does temperature affect solubility?

A

The solubility of most solid solutes increases as temperature increases

30
Q

How do precipitates form?

A

Precipitation reactions occur when a soluble and insoluble products combine to form an ionic solid called a precipitate

31
Q

What is the boiling point of pure water?

A

100 degrees celcius

32
Q

What is the boiling point of salt water?

A

102 degrees celcius

33
Q

Why is salt put on icy roads?

A

Using road salt is a means of freezing point depression, which means that road salt can lower the freezing temperature of the water.
