Discussion Report 9: Redox Titration: Winkler Method for Dissolved Oxygen Determination The three main objectives of the experiment are to (1) determine dissolved oxygen (DO) in water using the classical method (redox titration)‚ (2) discuss the chemistry behind the Winkler method for DO analysis and (3) describe the sampling technique for the analysis of DO in water sample. In the Winkler method‚ or Iodometry‚ the dissolved oxygen is made to react with Iodide ion to yield Iodine which will be titrated

Oxygen (O) Human beings obtain this element from the air. It enters a person’s bloodstream through the lungs. The blood carries oxygen to the cells of the body. In the cells‚ oxygen combines with chemicals obtained from food. Energy produced during this process makes it possible for each cell to perform its function in the body. Also‚ oxygen atoms are present in water and water is essential to all life. It is present in many organic compounds. While oxygen is necessary for life‚ oxygen as ozone

The initial research of sports science was to ensure energy levels and oxygen consumption to decrease fatigue and risks of injury (Hendricks). Latest in sports technology includes the RespiBelt. It acts as a free-weight made of elastic bands that strengthens breathing muscles. Breathing comes easy at rest‚ but as physical activity

In 2009‚ Google has created PiLab to improve people’s operation. PiLab initiated Project Oxygen to research the impact of managers on employees and methods to enhance management. Google’s problem now is how to implement the research to increase efficiency for management. There are three alternatives which are to study senior management and executives‚ providing guidance to team composition and to study the complete life cycle of managers. The criteria used to evaluate each alternative are whether

another substance. A solution can be a solid solution (e.g. an olivine)‚ a liquid solution for example an aqueous solution that results from the dissolution of sodium chloride solid crystals in water or it can be a gas solution (e.g. a mixture of oxygen gas and carbon dioxide gas in the air). This solution may be ideal or non-ideal. The type of solution whether it is ideal or non-ideal‚ will have a different thermodynamic function. Thermodynamics is a system where it is about a relation of conservation

Analysis: The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases‚ the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit

list of items‚ both tangible and non tangible‚ that trees give us. First of all‚ as we all know‚ trees are the most important and the only natural source of oxygen in the atmosphere. Without oxygen[->0]‚ life is not possible on earth. Trees consume the carbon dioxide[->1] from the environment and give out oxygen which balances the amount of oxygen and carbon dioxide[->2] in the atmosphere. In addition to this‚ the wood that we obtain from trees is used in making paper‚ building houses‚ making furniture[->3]
