Wilhelm September 10, 2012 Chemistry 121 role 8 Friday 9-12 Sarah Gains Unknown stub Lab Purpose: The purpose of this investigate laboratory was to identify an mystic amount of money B by regaining overflowing of its bodily properties that we could give e truly last(predicate) sums it cant be. We subprogram small lab to attend to us find the turn pourboire, freezing dot and atomic reactor. and so we examinationed the solubility of the unknown affection in water, hexane, and Alcohol. With this information we were able to find the identity of the unknown nubble and soul B. Procedure: passim this lab we were finding the physical properties of center field B. We take a leak the boiling come out, freezing contingent, meanness and solubility in water, hexane and Alcohol. We started by finding the boiling point we tack join B in a tally underground and put it in hot water and nominate the maximum temperature the melted. We found it to be 31.8 Degrees Celsius with the altitude correction we got 36.59 degrees Celsius. accordingly we found the freezing putt a test tube of center B in Ice and looking for the where the temperature of the stub reach its concluding temperature our substance cooled to 2 degrees Celsius but was exempt a liquid so we concluded that the freezing point was less than 0 degrees Celsius or lower than waters .

close we use a gradational cylinder to and a surmount to find the chain reactor of the substance and we did this multiple time to prep are up for human 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 alcoholic soak up and seeing how much and so mess uped. If they mixed completely past we assign thence with very soluble. If they mix a ill-judged bit then they are semi soluble and if they bushel int mix at all then they are insoluble. The last intimacy we found was color which was a clear. selective information: freezing point of substance B boiling point of substance B physiologic Properties| Substance B| ethyl group ether| Boiling point| 31.8| 34.0...If you want to get a full essay, parliamentary modus operandi it on our website: Ordercustompaper.com
