    I guess I am the only one who came here to share my very own experience. Guess what!? I am using my laptop for almost the past 2 years, but I had no idea of solving some basic issues. I do not know how to Download Cracked Pro Softwares But thankfully, I recently visited a website named wahabtech.net

Detection of unknown sugar sample solution

   Detection of unknown sugar sample solution  General Test:1 1.Benedict's Test Experiment  3ml sample solution and 2-3 ml Benedict's qualitative reagent are mixed in a dry clean test tube and boiled for 5 minutes. Observation  The mixture solution turns green, yellow and finally red. Inference  The supplied sample is of reducing sugar.  The red ppt. is Cu2O (I). Reactions : Reducing sugar+alkali—>Enediols Enediols+2 Cu2+---> 2Cu+ + acidic sugar 2Cu+ + 2OH– —-> 2CuOH 2CuOH +Heat —> Cu2O (red ppt) +H2 O General Test   2.Barfoed's Test Experiment  1 ml (5 drops) sample solution and 3 ml Barfoed's reagent ( a soln of cupric acetate and acetic acid) are mixed in a test tube and boiled in a boiling water bath for 3 minutes. Observation  A reddish ppt.is formed. Inference  The reducing sugar is a monosaccharide since ppt is formed within 3 minutes. Reaction : R–CHO + 2 Cu2+ +2H2O—-> R–COOH + Cu2O + 4H+ Confirmatory Tests : 1.Moore's Test Ex

       Cordaites is a reconstructed fossil plant/extinct plant (upto 30 mt high ) and it was originated during Upper Devonian , climaxed at Upper Carboniferous and declined at the beginning of Triassic period (about 225 million years ago ) .   Systematic position:            Division. ........Gymnosperms                  Class  .........Coniferopsida                        Order............Cordaitales                               Family........Cordaitaceae                                     Genus...... Cordaites This group of coniferous gymnosperms were named after Corda . Order Cordaitales comprises of a single family Cordaitaceae . A total of 4 genera and 26 species were discovered from Indian  Gondwana  Flora which are represented in the form of impression and compression of leaves ,seeds and permineralised woods. A large number of different form-genera of Cordaitales have been reported by different palaeobotanists from China ,Siberia ,North America,Europe ,
