Modified Winkler Method for Dissolved Oxygen Determination Tiffany T. Lee Department of Biological Sciences‚ College of Science University of Santo Tomas‚ Manila‚ Philippines 1008 Date of Submission: February 17‚ 2011 Abstract In this experiment‚ the Winkler Method was used to measure the dissolved oxygen (d.o.) in a water sample from the pond in the Arch of the Centuries which had the owl statues. Then‚ the amount of oxygen is determined through a series of reaction. Usually‚ Winkler

Plants Which Produce Oxygen at Night‚ Debunked. Can some plants produce oxygen at night? I hear you ask‚ after all the internet is filled with articles stating that plants suck as snake plant‚ and some types of daisies and others produce oxygen at night. But remember your primary school science classes‚ when you learnt that plants practice a ‘magical’ process called photosynthesis? A plant needs light and water‚ to turn carbon dioxide into carbohydrates‚ and oxygen is the waste product of this

a beneficial therapy for children with Cerebral Palsy? Background: Hyperbaric Oxygen Therapy (HBOT) is being promoted as a new therapy for children afflicted with cerebral palsy. It is being utilized by several specialized medical centers in the US‚ Europe and Canada. The rationale behind this therapy is inhalation of pressurized pure oxygen within a hyperbaric chamber‚ results in higher levels of dissolved oxygen within the blood (Liptak‚ 2005). Over 15 studies have been conducted to determine

equipment‚ the main bearing of rotary kiln supports the weight of full rotary part and impact loads producing by grinding media and materials. Therefore‚ the spherical bush burning of the main bearing directly affects the normal operation of the device‚ thereby affects the processing operation of the entire production line. The spherical bush of the sliding bearings in the actual production often burns watts‚ causing great loss. (1)The main failure mode of the rotary bearing is the roll surface

(Figure 1). For the next test‚ Dissolved Oxygen‚ we also created a bar graph to compare the values for the control and experimental groups. These results came in as statistically significant too‚ as the p-value was very low at .004. As for the overall mean values of the two groups‚ we found that the control group was oversaturated with oxygen at 102.78% while the experimental group was also slightly oversaturated at 101.55%.

Hydrogen is recognized as the simplest and lightest chemical element in the periodic table; even though it is identified as one of the top elements in abundance in the world (consisting of 0.9 percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves

The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are‚ however‚ a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound is ionic‚ then the name of the cation (usually metal) comes first‚ followed by the ’compound’ name of the anion. To find the compound name of an anion‚ replace the end of the
