Introduction The purpose of the experiment was to determine the melting points of compounds using a Mel-Temp device. The melting point of naphthalene‚ urea‚ and sulfanilamide are found. This is then followed by the measuring of an unknown compound‚ and an impure sample (a small amount of naphthalene mixed with the unknown). Experiment In the lab‚ the height of the chemical in the capillary was set to 2-3 mm thickness. The voltage at the Mel-Temp started at a low setting of 1.5-2. The heat was

Devastation in the war left countless soldiers and civilians with life threatening injuries and diseases. This devastation and destruction‚ led to the innovation of the three most important medicines in history namely Penicillin‚ Blood plasma and Sulfanilamide. These three innovations in the field of medicine helped save thousands of soldiers in World War II and are considered to be the most important medical advancements in the war. "Penicillin fought for the soldier as bravely as the soldier fought

THE EXPERIMENTS Joseph Mengele was very interested in genetics‚ particularly in twins. He carried out various experiments and tests‚ which were brutal and absolutely ferocious. They shock me so much‚ I find it so hard to believe a man was capable of such ghastly‚ cruel and barbaric actions. Some people still live today‚ to tell the horrific‚ terrifying stories of Mengele… who have experienced his cruelty first hand. Below are some true stories I have heard about through documentaries I have studied

inventions also became popular very quickly such as Broadcasts. Throughout the 1920’s there were different medical discoveries. A new type of drug to fight infections and viruses was discovered called the sulfanilamide drug. This drug and its different derivatives were known as Sulfa drugs. Sulfanilamide was tested on mice first‚ and because of it success‚ it was tried on a baby dying from an infection‚ obtaining positive results. These drugs became very popular and useful‚ along with the recently discovered
