strong and weak acids

Question 1

in aqueous solutions, acid molecules ionise and release what?

Answer 1

hydrogen ions (H+)

Question 2

what do strong acids do?

Answer 2

fully ionise in aqueous solutions

Question 3

what are 3 examples of strong acids?

Answer 3

hydrochloric acid, sulfuric acid and nitric acid

Question 4

what do weak acids do?

Answer 4

partially ionise in aqueous solutions

Question 5

what does a reversible reaction mean?

Answer 5

some of the acid molecules ionise, but not all

Question 6

do strong acids have a lower or higher pH than weak acids for a given concentration?

Answer 6

strong acids have a lower pH then weak acids

Question 7

why do strong acids have a lower pH then weak acids?

Answer 7

because strong acids fully ionise, producing a higher concentration of hydrogen ions

Question 8

as pH scale decreases by one unit, what happens to the concentration of hydrogen ions?

Answer 8

concentration of hydrogen ions decreases by 10 times

Question 9

what does the concentration of acids tells us?

Answer 9

the amount of acid molecules in a volume of solution

Question 10

does a dilute acid have fewer or more acids molecules in a given volume than a concentrated acid?

Answer 10

a dilute acid has fewer acid molecules then a concentrated acid
