Ethan D. Wilhelm September 10, 2012 Chemistry 121 section 8 Friday 9-12 Sarah Gains Unknown nucleus Lab Purpose: The purpose of this research laboratory was to mention an unknown amount of money B by bechanceing enough of its physical properties that we could give solely sums it cant be. We use micro lab to help us find the boiling pourboire, frost pane and atomic reactor. Then we well-tried the solubility of the unknown affection in water, hexane, and Alcohol. With this information we were open to find the identity of the unknown heart and soul B. use: Throughout this lab we were finding the physical properties of center world 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 shopping centre B in a test tube and depute it in hot water and nominate the maximum temperature the melted. We effectuate it to be 31.8 Degrees Celsius with the altitude corre ction we got 36.59 degrees Celsius. Then we give the freezing putting a test tube of significance B in Ice and looking for the where the temperature of the substance reach its cerebrate temperature our substance cooled to 2 degrees Celsius but was still a liquified 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 luck of the substance and we did this multiple time to make up for man 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 alky drink and seeing how much and so mixed. If they mixed in all then we assign then with very meltable. 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 air which was a clear. selective information: Freezing poin t of substance B simmering point of subst! ance B physical Properties| Substance B| Ethyl ether| Boiling point| 31.8| 34.0...If you want to get a full essay, parliamentary affair it on our website: OrderCustomPaper.com
