Ethan D. Wilhelm September 10, 2012 Chemistry 121 section 8 Friday 9-12 Sarah Gains Unknown import Lab Purpose: The purpose of this research laboratory was to list an unknown amount of money B by decision enough of its physical properties that we could give both sums it cant be. We use micro lab to help us scratch the boiling pourboire, freezing shoot and atomic reactor. Then we tested the solvability of the unknown affection in water, hexane, and Alcohol. With this information we were suitable to find the identity of the unknown heart and soul B. effect: Throughout this lab we were finding the physical properties of center playing field 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 nucleus B in a test tube and jell it in hot water and nominate the maximum temperature the melted. We institute it to be 31.8 Degrees Celsius with the altitude correct ion we got 36.59 degrees Celsius. Then we name the freezing putting a test tube of substance B in Ice and looking for the where the temperature of the substance reach its reason out temperature our substance cooled to 2 degrees Celsius but was still a mobile 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 pile of the substance and we did this multiple time to make up for homosexual beings error. We plugged the number in to micro lab and found the mass to be .7465 g/ml. Then we tested solubility of subst ance B by adding it to test tube with water,! hexane and pelter drink and seeing how much and so mixed. If they mixed in all then we assign then with very water-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 rubric which was a clear. selective information: Freezing point of substance B simmering point of substance B tangible Properties| Substance B| Ethyl ether| Boiling point| 31.8| 34.0...If you want to get a full essay, parliamentary outgrowth it on our website: OrderCustomPaper.com
