To determine the concentration of an ethanoic acid solution.

A-Level: Chemistry

In this experiment I will conclude the concentration of ethanoic acid solution. We are going to use domestic vinegar which was labelled as containing 5% acidity.

Equipments: -

 Burette 50cm3
 Pipette 25 cm3
 Pipette filler To fill the pipette
 Stand and clamp 2 utility clamps
 Volumetric flask 250cm3
 White tile One
 Funnel To put lithium hydroxide in burette
 beakers 500 cm3 ,have your acid

 conical flask To perform titration

Reagents: -
 Sodium hydroxide Concentration of 0.10 mol dm-3
 Ethanoic acid 150 cm3
 Acid/Base indicator 3-4 drops for each titration of phenolphthalein indicator.

Other liquid Solution: -
Water
Distilled water – to clean equipments between each titration.
Balanced Equation: -

CH3COOH + NaOH --> NaCH3COO + H2O
