2.3 The Concept of Strong and Weak

Question 1

strong acids ______ when dissolved in water

Answer 1

fully dissociate into ions

Question 2

what do strong acids do in water

Answer 2

fully dissociate into ions

Question 3

is there equilibrium when a strong acid forms

Answer 3

no

Question 4

what do weak acids do in water

Answer 4

partially dissociate into ions in water

Question 5

equilibrium of weak acids dissociating

Answer 5

lies very much to the left

thus K is a small number

Question 6

strong based in water

Answer 6

fully dissociate into ions

Question 7

does equilibrium form in strong acids dissociating in water

Answer 7

no

Question 8

weak bases in water

Answer 8

only partially dissociate into ions in water

Question 9

equilibrium of weak bases dissociating in water

Answer 9

lies very much to the left

thus K is a small number

Question 10

weak acid has _____ pH than a strong acid

Answer 10

higher

Question 11

weak base has _____ pH than a strong base

Answer 11

lower

Question 12

why does a weak acid have a higher pH than a strong acid

Answer 12

fewer H+ ions

acid has lower conductivity

reacts slower

Question 13

fewer H+ ions

acid has lower conductivity

reacts slower

Answer 13

weak acids

Question 14

does the quantity of alkali or acid needed for neutralise change depending on if it’s weak or strong

Answer 14

no
