Strong and weak acids

Question 1

example of three strong acids

Answer 1

nitric acid (HNO3), hydrochloric acid (HCl), sulphuric acid (SO4)

Question 2

example of three weak acids

Answer 2

carbonic acid (H2CO3), ethanoic acid (CH3COOH), citric acid (C6H8O7)

Question 3

how are strong acids different to weak acids

Answer 3

strong acids have a lower pH for a given conc.

Question 4

why are strong acids stronger than weak

Answer 4

because they fully ionise giving higher conc. of H+ ions

Question 5

as pH scale decreases by one unit, the H+ ions increase by…

Answer 5

10x

Question 6

what does the concentration of an acid tell us

Answer 6

the amount of acid molecules in a given volume of solution

Question 7

what will a dilute acid have

Answer 7

fewer acid molecules in a given volume than a con. acid even if the strength of the acid is the same

Question 8

difference between strong acid and concentrated acid

Answer 8

strong acid= fully dissociates H+ ions in aqueous solution.
concentrated= very high concentration of H+ ions in an aqueous solution
