CHAPTERS 11.1-11.6

Question 1

acids are proton…?

Answer 1

donors

Question 2

bases are proton…?

Answer 2

acceptors

Question 3

what is a monoprotic acid and give an example

Answer 3

monoprotic acids ionise in one step.
eg. HCl

Question 4

what is a diprotic acid and give an example

Answer 4

diprotic acids ionise in 2 steps
eg. H2SO4

Question 5

what is a triprotic acid and give an example

Answer 5

triprotic acids ionise in 3 steps
eg. H3PO4

Question 6

when is a full arrow used?

Answer 6

when a strong acid fulling ionises (or dissociates) in solution.

Question 7

when is an equilibrium arrow used?

Answer 7

when weak acids or bases only partially ionise (or dissociate) in solution

Question 8

what is the difference between strength and concentration?

Answer 8

strength refers to the extent of ionisation. concentration refers to mol dm-3

Question 9

acids + metal hydroxide ->

Answer 9

salt + water

Question 10

acid + metal carbonate->

Answer 10

salt + water+ carbon dioxide

Question 11

acids + metal->

Answer 11

salt + hydrogen gas

Question 12

what is the equation to measure pH?

Answer 12

pH = -log10 [H+]
[H+] = 10-pH

Question 13

what is the equation for the ionic product of water?

Answer 13

Kw = [H+] x [OH-] = 1 x 10-^14
