Finely dispersed drug droplets in water are prepared and their specific area and solubility are measured at 25°C. It is found that the emulsion has a specific area of 4.25×105 cm2/g and the solubility is 11.5% higher than the one of the bulk liquid. Calculate the size and the interfacial tension of the droplets, if the molar volume of the drug is Vmol = 22.3 cm3/mol. Assume that the drug has the density of water (1.0 g/cm3).

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
