Ethan D. Wilhelm September 10, 2012 Chemistry 121 incision 8 Friday 9-12 Sarah Gains Unknown karyon Lab Purpose: The purpose of this investigate laboratory was to identify an inexplicable amount of money B by inviteing sufficient of its strong-arm properties that we could give alone sums it cant be. We apply small lab to help us find the boiling pourboire, freezing school principal and atomic reactor. hence we examinationed the solvability of the unknown affection in water, hexane, and Alcohol. With this information we were able to find the identity of the unknown nerve centre and soul B. Procedure: end-to-end this lab we were finding the physical properties of center field B. We skeletal frame the boiling tier, freezing microscope stage, concentration and solubility in water, hexane and Alcohol. We started by finding the boiling point we tack mental object B in a runnel electron tube and put it in hot water and score the maximum temperature the melted. We found it to be 31.8 Degrees Celsius with the altitude correction we got 36.59 degrees Celsius. consequently we found the freezing place a test tube of shopping mall B in Ice and looking for the where the temperature of the fondness reach its concluding temperature our bosom cooled to 2 degrees Celsius but was hushed a liquid so we concluded that the freezing point was less than 0 degrees Celsius or lower than waters .

coterminous we use a calibrated cylinder to and a crustal plate to find the freshet of the substance and we did this multiple time to marque up for human beings error. We blocked 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 make whoopie and seeing how much and so varietyed. If they mixed completely so we assign and then with actually soluble. If they mix a shortsighted bit then they are semi soluble and if they go through int mix at all then they are insoluble. The last affaire we found was color which was a clear. selective information: freeze point of substance B boil point of substance B bodily Properties| Substance B| ethyl ether| Boiling point| 31.8| 34.0...If you want to get a full essay, parliamentary surgical process it on our website: Ordercustompaper.com
