Water Purification
Aim
The aim of this practical is to analyse a sample of water and then to purify the water through a process of purification.
Background information
Water purification is the process of removing impurities from water to make it suitable for drinking. In this practical, you will measure the pH of a water sample, remove impurities by distillation, and check the purity of the water by measuring the boiling point.
How is the boiling point of the distilled water determined?
by analysing the mass balance
by heating the water until it boils and measuring the temperature
by measuring the pH of the water sample
by weighing the cooled evaporating basin
|
Which piece of equipment is used to collect the distilled water?
tripod and gauze
boiling tube
evaporating basin
conical flask with delivery tube and bung
|
What is the pH of pure water?
7
5
4
9
