Salt Lab

Modeling Effective Dose: Salt Tasting lab Purpose The purpose of this lab is to see at what measurements (of salt) can the salt be detected by taste. Abstract The science of toxicology is based on the principle that there is a relationship between a toxic reaction (the response) and the amount of poison received (the dose). An important assumption in this relationship is that there is almost always a dose below which no response occurs or can be measured. A second assumption is that once a maximum...

Saline Salt

Robert Lawrence and Edmund Stephens, two graduate students of geology from Columbia University, organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1,000 grams of seawater contains approximately 35 grams of various salts, the two men pictured limitless wealth for them by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so, the men decided to begin producing it. They picked New Iberia, Louisiana as the ideal...
