Task 2 & 3:
A. Pile the seaweed up on the tin lid supported on a tripod and begin heating with a strong Bunsen flame. It may have to be added a portion at a time during the heating, given the quantity to be reduced to ash. When all has been turned to ash, about a dessertspoonful of residue will remain.
During the experiment we piled the seaweed into a tin container and placed it on top of a tri-pod which was placed over a Bunsen burner allowing the seaweed to burn and inevitably turn into ash so the extracting of iodine can begin.
It is important to make sure that not too much seaweed is added at any one time as certain sizes of seaweed pops therefore it is important to ensure that the appropriate safety clothing is worn including safety goggles and lab coat to avoid getting potentially hot pieces of seaweed either in your eyes or on your clothes.

Boil the ash with about 20cmᶟ of purified water in a beaker, and filter while hot. Collect the clear filtrate in a second beaker and allow to cool.
We then placed the ash into distilled water and allowed it to boil once again over the Bunsen burner to allow the extraction of iodine to begin once this has complete all the iodine can be extracted from the water using a funnel.
Ensure that the beaker is allowed a sufficient amount of time to cool before handling it as you could burn yourself. Additionally it is important to ensure that when boiling the liquid all the water is boiled away as there will then be no iodine left to filter to complete the experiment.
C. Turn of the Bunsen
