Solutions, Dilutions and Body Fluids

Question 1

Tonicity?

Answer 1

the ability of an extracellular solution to make water move into or out of cell by osmosis

Question 2

4 main properties of water?

Answer 2

• polarity
• adhension
• cohesion
• surface tension

Question 3

Whats a solution?

Answer 3

a solution is composed of a solvent and solute

Question 4

What is a solute?

Answer 4

the minor component of a solution which is dissolved

Question 5

What is a solvent?

Answer 5

the major component of solution which is present in the greatest amount

Question 6

Electrolytes and solutes?

Answer 6

electrolytes are molecules that ionise completely in a solution and therefore conduct electricity

Question 7

Non-electrolytes and solutes?

Answer 7

non-electrolytes do not ionise in solutions and therefore do not conduct electrical activity

Question 8

A saturated solution?

Answer 8

contains the maximum amount of solute that will dissolve at that temperature

Question 9

A unsaturated solution?

Answer 9

contains less than maximum amount of solute that can be dissolved in that temperature

Question 10

Relate properties of gases to pressure, volume and temperature?

Answer 10

at constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure
