    Water purified by means of reverse osmosis, and other demineralizing procedures is not healthy for human consumption, and the distribution of this water is unethical because of these health issues. It turns out that the purification of water removes vital nutrients and minerals, not just the toxins in the water. Water purified by reverse osmosis is in fact water in its purest form, almost 100% H2O, but that does not make it healthy for the human body, which requires minerals which can only be sufficiently absorbed by water that has not been purified. “When we drink purified water, we are consuming a pure chemical substance, H2O. Pure chemical substances of any kind are not found in nature collected together, but instead are always mixed with other substances. Because of its extreme purity, purified water absorbs carbon dioxide from the air, which makes it acidic and even more aggressive at dissolving the alkaline substances it comes in contact with.” (Purified Water and its…

    to urea and the liquid is then furthurly purified. Then, the second reactor receives the gas from the first reactor and recycles the solution. Conversion of carbon dioxide to urea is approximately 60% at a pressure of 50 bar (g). The solution is then purified in the same process as was used for the liquid from the first reactor. Step 2 - Purification The major impurities in the mixture at this stage are water from the urea production reaction and unconsumed reactants (ammonia,…

    to incorporate with the purified water in the next stage. Make sure you are wearing the appropriate safety clothing, e.g. goggles, a lab coat and closed-toed shoes as some of the chemicals used in this experiment can be harmful and working with heat means there is a risk of burning. Ensure that you add enough seaweed to the tin at the start of heating, taking into consideration that it will reduce in size as it turns to ash. Also try not to select and large pieces or ‘pods’ of seaweed as they…

    was brought to the hood and 7.0g of pyridinium tribromide was added and then stirred for about 30 minutes with a watch glass as a cover. While stirring, 10% sodium bisulfite was added in 1ml increments until the orange/red color disappeared or was less intense. After, the solution was cooled in an ice water bath. Once crystals formed, the solution was filtered using a funnel. The product was then recrystallized from 95% ethanol and water. In order to do this, the amount of ethanol used was…

    A magnetic stirrer was placed into the beaker and the reaction was heated in a 50℃ water bath. The reaction mixture was heated and stirred for 5 minutes until the salicylic acid dissolved. The mixture was set aside to cool down to room temperature and crystallize in the beaker. Afterwards 6 mL of cold deionized water was added to the crystals (aspirin). The crystals were separated from the mixture through vacuum filtration using a Hirsch funnel. The mixture was washed with 0.5 mL of cold…
