Ethan D. Wilhelm September 10, 2012 Chemistry 121 section 8 Friday 9-12 Sarah Gains Unknown burden Lab Purpose: The purpose of this research laboratory was to refer an unknown amount of money B by purpose enough of its physical properties that we could give all(prenominal) sums it cant be. We use micro lab to help us describe the boiling pourboire, frost stage and atomic reactor. Then we time-tested 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. mathematical function: Throughout this lab we were finding the physical properties of center electron orbit 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 meat B in a test tube and format it in hot water and nominate the maximum temperature the melted. We bring it to be 31.8 Degrees Celsius with the altitude correction we got 36.59 degrees Celsius. Then we represent the freezing putting a test tube of meat B in Ice and looking for the where the temperature of the substance reach its last-place temperature our substance cooled to 2 degrees Celsius but was still a lucid 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 surge of the substance and we did this multiple time to make up for homo 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 te! st tube with water, hexane and alcoholic drink and seeing how much and so mixed. If they mixed exclusively 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 annotate which was a clear. selective information: Freezing point of substance B simmering point of substance B corporeal Properties| Substance B| Ethyl ether| Boiling point| 31.8| 34.0...If you want to get a full essay, parliamentary action it on our website: OrderCustomPaper.com
