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

Chronic obstructive pulmonary disease or COPD is a slow and progressive obstruction of the airways. There are two categories of COPD. These are emphysema‚ a condition where there is abnormal and permanent destruction and enlargement of the alveoli. Chronic bronchitis is a productive cough and inflammation of the bronchi and other lung changes. Smoking and second hand smoke exposure are the main contributors to this disease. Other contributing factors can be environmental air pollution and genetics

the lungs. The trachea pulls air into the lungs via the bronchi. The bronchioles then are a functional branch of the bronchi. The tiny pockets of alveoli store air briefly in order for oxygen to be absorbed in the bloodstream. Through the alveoli the gas exchange into the lungs occurs. Pathophysiology of COPD COPD stands for Chronic Obstructive Pulmonary Disease. It is typically caused by inhaled irritants such as tobacco smoke. It is a chronic inflammation of the airways‚ lung tissue‚ and pulmonary

What is COPD? Chronic Obstructive Pulmonary Disease is a progressive disease that constricts airways and dramatically hinders a person’s ability to breathe. It affects around 13% of Australians aged 40 or over. It causes mucus or blood-filled coughing‚ chest tightness and severe shortness of breath. The disease is comprised of Chronic Bronchitis‚ Asthma and Emphysema‚ with the seriousness of it being judged by four levels‚ each level increasing in severity. To this day‚ there is no known cure

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

disease Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease that results in obstructed airflow from the lungs. When a person takes a breath‚ air travels down the windpipe into airways. These airways scatter into smaller‚ much thinner tubes that end in a bunch of tiny air sacs. These air sacs stretch and inflates when a person breathes in and then deflates when the person breathes out. When a patient is diagnosed with COPD‚ their lung function is greatly lessened with air
