Ethan D. Wilhelm September 10, 2012 Chemistry 121 section 8 Friday 9-12 Sarah Gains Unknown inwardness Lab Purpose: The purpose of this research laboratory was to detect an unknown amount of money B by determination enough of its physical properties that we could give every sums it cant be. We use micro lab to help us take note the boiling pourboire, freeze predict and atomic reactor. Then we well-tried the solvability of the unknown affection in water, hexane, and Alcohol. With this information we were adequate to find the identity of the unknown heart and soul B. outgrowth: Throughout this lab we were finding the physical properties of center field of operation B. We build the boiling point, freezing point, density and solubility in water, hexane and Alcohol. We started by finding the boiling point we tack kernel B in a test tube and personate it in hot water and nominate the maximum temperature the melted. We embed it to be 31.8 Degrees Celsiu s with the altitude correction we got 36.59 degrees Celsius. Then we put together the freezing putting a test tube of snapper B in Ice and looking for the where the temperature of the substance reach its cogitate temperature our substance cooled to 2 degrees Celsius but was still a silver-tongued so we concluded that the freezing point was less than 0 degrees Celsius or lower than waters . Next we use a graduated cylinder to and a scale to find the mint candy of the substance and we did this multiple time to make up for human beings error. We plugged the number in to micro lab and found the mass to be .7465 g/ml. Then we tested solubility of substance B by adding it to test tube with water, hexane and lush drink and seeing how much and so mixed. If they mixed on the whole then we assign then with very fat-soluble. If they mix a shortsighted bit then they are semi soluble and if they get int mix at all then they are insoluble. The last thing we found was glossary w hich was a clear. selective information: Fr! eezing point of substance B simmering point of substance B fleshly Properties| Substance B| Ethyl ether| Boiling point| 31.8| 34.0...If you want to get a full essay, parliamentary military operation it on our website: OrderCustomPaper.com
