many ml of 1.0
moll-1 of
concentrated
solution should be
made up to 0.5l to
obtain the correct
concentration?
- Answer
- Answer

- Principals Of Chemical
Reactions
- C1V1 = C2V2
- Balanced Chemical Equation = Stoicheometric Equation
- QUANTITATIVE ANALYSIS
- Uses stoichiomteric equations to establish amount of a
given element compound in a sample
- VOLUMETRIC ANALYSIS
- VOLUME
- Determine the concentration of a solution using a STANDARD SOLUTION
- Standard solutions prepared from PRIMARY STANDARD
- Properties of a Primary Standard
- Common Primary Standards
- Properties of a Primary Standard
- Standard solutions prepared from PRIMARY STANDARD
- ACID/BASE TITRATION
- C1V1P1 = C2V2P2
- Example 1
----------------
What is the
concentration of
citric acid ( a
triprotic acid) in
lemon juice if 10ml
of the juice requires
12.0ml of 0.050
moll-1 sodium
hydroxide for
complete
neutralisation.

- Calculate unknown concentration of acid or base
- Colour change
= Endpoint
(Indicator)
- C1V1P1 = C2V2P2
- REDOX TITRATION
- C1V1/n1 = C2V2/n2
- Example
- Answer
- Answer
- Example
- Acidified Potassium
Permanganate commonly used
(SELF indicator)
- iodine also used with starch as
indicator
- Based on oxidation/reduction reaction
- C1V1/n1 = C2V2/n2
