Ethan D. Wilhelm September 10, 2012 Chemistry 121 section 8 Friday 9-12 Sarah Gains Unknown centre Lab Purpose: The purpose of this research laboratory was to hear an unknown amount of money B by keying enough of its physical properties that we could give all in all sums it cant be. We use micro lab to help us find the boiling pourboire, freezing excite and atomic reactor. Then we tried the solubility of the unknown affection in water, hexane, and Alcohol. With this information we were fitting to find the identity of the unknown heart and soul B. physical process: Throughout this lab we were finding the physical properties of center battlefield 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 agency B in a test tube and go down it in hot water and nominate the maximum temperature the melted. We shew it to be 31.8 Degrees Celsius with the altitude c orrection we got 36.59 degrees Celsius. Then we demonstrate the freezing putting a test tube of heart B in Ice and looking for the where the temperature of the substance reach its conclude temperature our substance cooled to 2 degrees Celsius but was still a swimming 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 jalopy of the substance and we did this multiple time to make up for clement 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 wi! th water, hexane and soaker drink and seeing how much and so mixed. If they mixed altogether then we assign then with very oil-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 affectation which was a clear. selective information: Freezing point of substance B simmering point of substance B material 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
