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

Absolute values In an absolute value‚ everything with it is counted as a positive. ∣-a∣ = --a= a ∣a∣ =a In an equation‚ absolute values have two possibilities when talking about equations ∣a+b∣ =x = a+b=x = a+b= -x e.g. Solve ∣x-4∣=8 x-4=8 OR x-4= -8 x=12 x=-4 Sub both answer into the equation ∣12-4∣ =8 OR ∣-4-4∣ =8 8=8 8=8 Both solution re true so x=12 or x=-4 Absolute inequalities (method 1) If ∣a+b∣ ≤x∣a+b∣
