conditions for production of glucose by fermentation
temperature of 35. Catalyst of yeast. process - distillation t purify. Anerobic
1 of 14
why is a temperature of 35 degrees used in fermentation?
the optimal temperture for yeast to grow and reproduce. lower means lower production and higher could denature and kill yeast.
2 of 14
why is is anaerobic?
produce ethanol an carbon dioxide, aerobic condtions produce water and carbon dioxide.
3 of 14
what is a biofuel?
A fuel produced from renewable biological resources.
4 of 14
an advantage of a biofuel
renewable but not a made from crude oil.
5 of 14
what is acarbon neutral process?
A process in which there is no net overall carbon emissions to the atomosphere
6 of 14
what do you get when you distill a primary alcohol?
you get an aldehyde
7 of 14
what happens when you put an aldehyde under reflux?
you get a carboxylic acid
8 of 14
what happens when you put a primary alcohol under reflux?
you produce a carboxylic acid
9 of 14
what happens when you put a secondary alcohol under reflux?
you produce a Ketone
10 of 14
When using tollens reagent, what do you expect to see if a aldehyde is present?
leave a silver mirror around the test tube (aldehyde has been oxidised)
11 of 14
when using tollens reagent, what do you expec to see if a ketone was present?
No change
12 of 14
what would you expect to see when using Fehlings solution when an aldehyde is present?
A brick red precipitate
13 of 14
what would you expect to see when using Fehlings solution when a ketone is present?
No change
