Anhydrous sodium sulfate was added to the filtered organic solution to absorb excess water. Although water has a higher affinity towards sodium sulfate than cyclohexanol‚ excess anhydrous sodium sulfate may lead to the absorption of cyclohexane and thus loss of product. Anhydrous sodium sulfate absorbs water due to its polarity and therefore may also absorb cyclohexanol because of its polar O-H bond. If too much anhydrous sodium sulfate was added to the solution‚ part of the product would be absorbed

Sodium is a metal from group 1 of the periodic table‚ this is a metal which reacts when it needs to‚ this metal has a low melting and boiling point‚ also it is very dense‚ this shows that when reacting with other substances it will be different and this is because it will not react the same the whole time. The other thing is that this elements electron configuration is 11 which is quite low when comparing them to the other elements in the periodic table. However this metal is more reactive than
