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

Separation Lab Purpose: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. Sea sand‚ table salt‚ and two other unknown substances will be separated using the separation techniques in order to demonstrate

Separation of a Mixture Do-Your-Own-Lab What you will need to do: 1. Create a flow chart for the separation of your unknown mixture – BERFORE doing lab 2. Create data table – BEFORE doing lab 3. Do lab 4. Analyze data – calculate percent composition of your unknown mixture = 15 points = 30% 5. Write a complete lab report = 35 points = 70% 1. A flow chart is often used to illustrate the steps involved in the separation of a mixture. Flow charts are constructed BEFORE

Experiment 1 Separation of Mixtures Summary of Principles: Most of the materials we encounter in everyday life are not pure substances. Many materials such as sand are formed from physical combination of various substances‚ and are called mixtures. Mixtures can be classified into homogeneous and heterogeneous. The purpose of this lab is to learn how to separate individual components from a mixture through decantation‚ filtration‚ distillation‚ and crystallization. Pre-Lab Questions: Attached

Sand Density Lab- Nick Schlosser I. Overview- Finding the volume of regular shapes and irregular shapes using different methods like the water displacement method. Procedure- See data chart III. A.)With a ruler of calipers calculate volumes of regular and irregular objects- fill in chart. B.) Record data from another group to compare data for same object. Preliminary questions- 1. Explain how you propose we go about measuring the volume of sand(as sand has air around it. What

Procedure: This experiment consisted of different processes to separate a mixture of solids into the four individual solids: sand‚ benzoic acid‚ iron fillings‚ and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet

Industrial Separation Research a) Identify a mixture that is separated industrially: Olive oil b) Identify which ‘sphere’ it is obtained from: Biosphere c) Identify the industrial separation processes used on this mixture: Crushing/grinding: The olive fruit is crushed and ground by a metal hammer in a mill to make a paste. Beating: The olive fruit paste is added to water is additionally beaten to extract more oil from the olive cells. Salt can be used to assist osmotic breakdown [of the cells]

Mixture separation Lab I am one of the chemists assigned to design a cost effective procedure for handling the CARBOSE separation and recovery and hazardous waste disposal. The difficulties were trying to figure out is how we can effectively separate Carbose‚ sand‚ and naphthalene? The hypothesis we chose to solve this problem was if we put the mixture into water‚ alcohol‚ and mineral spirts‚ then in each solution one or more substance will not dissolve‚ will be visible‚ and also able to separate

Lab one is designed to determine fifteen sediment samples average grain size‚ sorting by size and mineralogy‚ rounding‚ sphericity‚ and Quartz/Feldspar/Lithic content as well as minerals present in each sample. In order to view the sample a stereoscope and light source is required. On the base of the stereoscope there is an insert that can either be black on one side and white when flipped to the other side. This insert can make viewing light or dark color samples easier due to the inserts backdrop

The purpose of this lab was to model the significant differences in density that oceans experience when glaciers and polar ice caps melt. It demonstrated that the variation in density greatly affects salt water. I discovered that the increase in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh
