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 response is reached any further increases in the dose will not result in any increased effect.
This lab was away to text the toxicology of the salt and our reactions to it. Since sodium-chloride is nontoxic our response to the dosage was measured by taste. This same method can be seen in medical studies for new drugs. Instead of students the doctors use mice and they test for the mice’s reaction to the medicine. Instead of testing the mice’s taste, they look for negative/positive side effects the mice might have
Intro
Different salts can elicit all five basic tastes, e.g., salty (sodium chloride), sweet (lead diacetate, which will cause lead poisoning if ingested), sour (potassium bitartrate), bitter (magnesium sulfate), and savory (monosodium glutamate). In our experiment we used non toxic sodium chloride, known as common kitchen salt.
Many ionic compounds can be dissolved in water or other similar solvents. The exact combination of ions involved makes each compound have a unique solubility in any solvent. The solubility is dependent upon how well each ion interacts with the solvent, so there are certain patterns. Salt of sodium is soluble in water. However, ions that bind tightly to each other and form highly stable lattices are less soluble, because it is harder for these structures to break apart for the compounds to dissolve. For example, most carbonate salts are not soluble in water, such as lead carbonate and barium carbonate. Soluble carbonate
