method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater is essential for

encountered‚ but still knowledge on how fast these occur and the factors affecting it were still insufficient. This study aimed to determine the different factors affecting the rate of reaction and how these factors affected it. An experiment named iodine clock reaction was done to answer the questions raised. In this study the reaction of iodide ion and peroxodisulfate (VI) ion was analyzed with the help of thiocyanate ion. The experiment was divided into three parts. First‚ second‚ and third parts

Lab #1: Melting Points of Organic Compounds Report Form May 15‚ 2014 1. A “Melting Point Range” refers to the range of temperature at which a solid melts into its liquid state. 2. Pure compounds have narrow or ‘sharp’ melting point ranges‚ 1°C or less if the compound is very pure. A less pure compound exhibits a broader melting point range‚ between 3°C to 10°C as well as a depressed or lower range. 3. Crushing the sample allows for greater surface area-to-volume ratio of the powder‚ this

Lung cancer kills more people in one year than all criminal and accidental deaths combined. These statistics are shocking‚ but the good news is that people are now well-informed about the risks connected to lung cancer. They know that their risk of contracting this terrible disease decreases if they either stop smoking or do not smoke at all. Unfortunately‚ the same cannot be said about other types of cancer. Many people are not aware that their everyday behavior can lead to the development of these

By insisting it was not worth my time to try‚ I could dissociate from my failures and blame them on my lack of interest or the activity’s low level of importance. This mindset went unchallenged throughout elementary and middle school when many of my chosen pastimes required minimal skill. It was not until high school that I began to feel

I am the most amazing person on earth. Do you know why I am so great? I am almost godly because of my great skill of tetherball. I hit the ball so hard that the post will fall over. Sometimes my arms power is so great that the string snaps. After snapping the ball would travel 300 feet before landing so the crowd members have a special spot called a splash zone. It was made just for me! The only thing that can compare to my power is the gods themselves! Maybe even my power is beyond this world
