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

18
Q

titration

A

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

19
Q

standard solution

A

a solution of accurately know concentration

20
Q

aliquot

A

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

21
Q

titre

A

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

22
Q

strong acids properties

A
  • completely ionise in water
  • many ions are formed in solution
  • represented by a forward arrow ->
23
Q

weak acids properties

A
  • do not completely ionise
  • few ions are formed in solution
  • represented by a double arrow ⇌
24
Q

concentration

A

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

25
Q

conductivity

A

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

26
Q

metal oxides

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

27
Q

metal oxides properties

A

solid - usually insoluble - form alkaline solutions if dissolved

28
Q

non-metal oxides

A

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

29
Q

non-metal oxides

A

gas - insoluble - form acidic solution when dissolved in water

30
