Question 17

acid-base indicators

Answer 17

weak acids/ base that exist in equilibrium with their conjugate pair

Question 18

titration

Answer 18

determining the unknow concentration of a stated reagent also known as volumetric analysis

Question 19

standard solution

Answer 19

a solution of accurately know concentration

Question 20

aliquot

Answer 20

a solution ( of fixed quantity) that is transferred using a volumetric pipette

Question 21

titre

Answer 21

an amount of solution ( of variable quantity) that is delivered using a burette

Question 22

strong acids properties

Answer 22

• completely ionise in water
• many ions are formed in solution
• represented by a forward arrow ->

Question 23

weak acids properties

Answer 23

• do not completely ionise
• few ions are formed in solution
• represented by a double arrow ⇌

Question 24

concentration

Answer 24

strength: how completely an acid/ base ionises in solution
concentration: total amount of acid/ base dissolved in a given solution
concentration doesn’t impact strength

Question 25

conductivity

Answer 25

strong acid- low pH + high conductivity strong base - high pH + high conductivity

Question 26

metal oxides

Answer 26

compounds containing a metal and oxygen in the form of the oxide ion

Question 27

metal oxides properties

Answer 27

solid - usually insoluble - form alkaline solutions if dissolved

Question 28

non-metal oxides

Answer 28

composed of non-metals and oxygen in the form of oxide ions O2-

Question 29

non-metal oxides

Answer 29

gas - insoluble - form acidic solution when dissolved in water

Question 30

non-metal oxides + water

Answer 30

oxyacids
