Strong and Weak Acids

Question 1

What is a dilute solution?

Answer 1

Contains a small amount of solute in a given volume of solution.

Question 2

What is a concentrated solution?

Answer 2

Contains a large amount of solute in a given volume of solution.

Question 3

What is a strong acid?

Answer 3

Ionise almost completely in water
i.e. a large proportion of the acid molecules dissociate to release H+ ions - tend to have low pH
Examples
Sulfuric - H₂SO₄
Hydrochloric - HCI
Nitric - HNO₃

Question 4

What is a weak acid?

Answer 4

Partially ionise in solution 
i.e. only a small proportion of the acid molecules dissociate to release H+ ions - pH tend to be around 2-6
Examples
Ethanoic -CH₃COOH
Citric -  C₆H₈O
Carbonic - H2CO3
