5- Oxidation Of Ethanol/Primary Alcahol Flashcards
1
Q
Describe the method of oxidising ethanol - CP5
A
2
Q
What do anti bumping granules do
A
Prevent vigorous/Violent and uneven boiling by providing a surface area for nucleation = making small bubbles form instead of large bubbles
3
Q
What would you see when oxidising a primary Alcahol under reflux
A
Orange to green
Cr2O7(2-) to Cr(3+)
4
Q
What things must you ensure when heating under reflux
A
Open at top
Water in bottom + out top of condenser
Anti-Bumping granules
No gap between pear shaped flask + condenser
5
Q
Describe diagram of heat under reflux
A
6
Q
Describe apparatus for distillation
A
7
Q
Where must the bulb of the thermometer be in distillation
A
At T junction connecting to condenser = to measure correct boiling point
