    potassium and chloride is an ionic bond. The potassium becomes a cation and the chloride an anion. The potassium end of the molecule becomes slightly positive and the other end slightly negative. Na – sodium contains metallic bonding. It has a high melting due to the bonding and has strong bonds. Each sodium atom is being touched by eight other sodium atoms and they all share electrons between the nuclei and shells. The electrons can move freely within the sodium metal and therefore can conduct electricity

    coursework I have been investigating the synthesis of Aspirin and checking for presence and purity of Aspirin. Throughout this coursework we have looked at the history of Aspirin; industrial manufacturing; making salicylic acid; the preparation of Aspirin; recrystallization and purity; melting point; thin layer chromatography (TLC) and titration of Aspirin. I’ve learned a lot about Aspirin‚ how it works and how it is made. We found out that the Aspirin we made and used was actually very pure when we

    Homeostatic Mechanism using the Comparitive Melting-Point Method for two Crab Species. Abstract Two crab species‚ Plagusia and Cyclograpsus‚ were collected from a local estuary in the littoral and deep water zone for osmoregulation studies. To examine differences in osmoregulatory mechanisms among the species‚ haemolymph of the specimens was extracted once they were acclimated to varying concentrations of seawater. Using the comparative melting-point‚ capillary tubes were filled with small samples

Isolation of Aspirin: The organic filtrate was extracted through a separatory funnel with 32 mL 5% sodium bicarbonate to produce an aqueous layer and a dichloromethane layer. 7.2 mL 6 M hydrochloric acid were added to the aqueous layer until the pH was 2. The mixture was then cooled in an ice/water bath for 10 minutes. The aspirin was collected by vacuum filtration. After it dried‚ it yielded 0.93 g (30.9 % of original Panacetin)
