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 severalize 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 start the boiling pourboire, frost drive and atomic reactor. Then we tried the solvability of the unknown affection in water, hexane, and Alcohol. With this information we were competent to find the identity of the unknown heart and soul B. part: 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 heart B in a test tube and point it in hot water and nominate the maximum temperature the melted. We assemble it to be 31.8 Degrees Celsius with the altitude correction we got 36.59 degrees Celsius. Then we set up the freezing putting a test tube of core group B in Ice and looking for the where the temperature of the substance reach its terminal temperature our substance cooled to 2 degrees Celsius but was still a fluidness 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 circumstances of the substance and we did this multiple time to make up for gracious 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 deluge drink and seeing how much and so mixed. If they mixed entirely 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 change which was a clear. selective information: Freezing point of substance B simmering point of substance B strong-arm Properties| Substance B| Ethyl ether| Boiling point| 31.8| 34.0...If you want to get a full essay, parliamentary number it on our website: OrderCustomPaper.com
