EXPERIMENT 11: DETERMINATION OF DISSOLVED OXYGEN IN A WATER SAMPLE (WINKLER METHOD) INTRODUCTION In an alkaline solution‚ dissolved oxygen will oxidize manganese(II) to the trivalent state. 8OH-(aq) + 4Mn2+(aq) + 2H2O(l) －－＞ 4Mn(OH)3(s) The analysis is completed by titrating the iodine produced from potassium iodide by manganese(III) hydroxide. 2Mn(OH)3(s) + 2I-(aq) + 6 H+(aq) －－＞ 2Mn2+(aq) + I2(aq) + 6H2O(l) Sodium thiosulphate is used as the titrant. Success of the method is critically

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the
