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

common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in a liquid. A liquid and a gas can also be dissolved in a liquid solution. c. Solid Solution- is a mixture of solids spread equally throughout one another. Metal is an example of a solid solution at room temperature. 3. Solubility is the ability of one compound to dissolve in another compound. 4. a. Temperature - Basically‚ solubility increases with temperature. It is the case for most of the solvents

However‚ for a metal ion indicator to be suitable in n EDTA titration‚ it must not bind as strongly with metal ions as EDTA does. Murexide is therefore suitable. AIM The aim of this experiment is to determine the percentage of nickel in a nickel(II) salt using EDTA. METHOD The following apparatus was collected: 50cmᶟ burette ●Glass stirring rod 20cmᶟ pipette ●Hydrated nickel(II) sulphate (NiSO₄.6H₂O) 100cmᶟ standard flask ●Standardised 0.10moll⁻¹ EDTA solution 250cmᶟ conical flask ●1 moll⁻¹ ammonium

world that are soluble‚ however‚ these chemicals have to follow a set of rules to determine how soluble each chemical is and if it is at all. This is what we call solubility laws. These laws show what chemicals are soluble and which ones are insoluble. They also describe what chemicals can be dissolved and what chemicals cannot dissolve. These chemicals are them recorded on Solubility tables which list solubility and how soluble the chemicals are. According to Busch (2015) the Solubility Rules are as
