3.0g of salicylic acid was weighed then 3.0mL of acetic anhydride and 6 drops of 85% H3PO4 were added to it. The mixture was warmed over a water bath for 5 minutes while stirring. After warming, 20 drops of distilled water was slowly added. 15mL of water was added then the solution was heated until it became clear. It was allowed to cool and was placed in an ice bath until the solution becomes cloudy. Using pre-weighed filter paper, the mixture was filtered and was allowed to dry in the filter paper.

For each of the 3 acceptable trials, enter the precise volume in milliliters of sodium thiosulfate solution used in

We usually think of the Grand Canyon in terms of its rocks, and the story and history that they can contain, spanning as far back as half of the Earth’s age. There is more to this canyon though than the rocks, as it is still active as a forever changing landform, due to the power of running water. The Colorado River has carved out the Grand Canyon in just the last nine million years. In fact, the river itself carries about half a million tons of sediment through the Grand Canyon each and every day. There are a number of different river types that will be talked about, and how exactly they have effected their environment and made changes in the landscapes.

The dark, navy blue colored graph represented the absorbance curve for the S1 sample. The red colored graph represented the absorbance curve for the S2 sample. The green colored graph represented the absorbance curve for the P1 sample. The purple colored graph represented the absorbance curve for the P2 sample. The gaps between the P2 curve was due to the oversaturation that led to the inconclusive spectrophotometer readings. The blue colored graph represented the absorbance curve for the P1 low salt sample. The orange colored graph represented the absorbance curve for the P2 low salt sample. The light blue colored graph represented the absorbance curve for the P1 medium salt sample. The light pink colored graph represented the absorbance curve for the P2 medium salt sample. The light green colored graph represented the absorbance curve for the P1 high salt sample. The light purple colored graph represented the absorbance curve for the P2 high salt

I conducted a survey of Pulaski county residents to get their opinion about the Pulaski county water supply. The purpose of the survey is to get others viewpoint of Pulaski County drinking water so that we can improve our waters system. In the Article “Arkansas Rivers is Too Polluted to Touch” written on April 24, 2000, it states “The river is fairly clean as it flows into Wichita, but by the time it leaves the city, the water is so dirty it is not safe for wading, fishing and touching, said Tom Stiles, chief of the office of planning and prevention at the Kansas Department of Health and Environment. The river also is not safe for canoeing, kayaking or water skiing.” Have Arkansas Rivers improved within 14 years? This question will help us to see how far Arkansas Rivers have come since the year 2000. According to Carl Safina in “Song for the Blue Ocean” he discussed how pollution can interfere with not only wildlife and aquatic animals, but humans as well. Pollution can get into our water system causing bacteria and diseases. These waters are the same that runs in our faucets and pipelines. I will discuss resent studies of central Arkansas water quality later in the survey report.

Hydrologic studies has always been the subdiscipline of environmental science that has most intrigued me; probably because the eco- and geological systems that comprise surface and shallow groundwater systems are so inexorably entwined and very delicate. Both of the virtual labs were interesting, and paint a clear picture of how we affect our hydrosphere and how that, in turn, affects us. Spotsylvania County and the city of Fredericksburg share four water treatment facilities that pull water from the Mott's Run Reservoir, the Ni River, and the Rappahannock River, which is the largest river in the local area, the other two being smaller tributaries that feed into it. The Rappahannock River is a significant body of water, providing the potable water for roughly a quarter-million people. Toward the coast the river sees mostly recreational and some light industrial use, and further upstream it is affected by many small to midsized agricultural operations that take place on the land adjacent to the river.

The same type of experimental process was used in the other experiments of temperature, and enzyme, substrate, and ionic concentration. For example, for temperature, they replaced the distilled water in the cuvettes with water of different temperatures of 3, 15, 25,37,and 100 degrees Celsius. Then, after the colorimeter was calibrated, the absorbance and transmittance of the data was collected for 2 minutes in increments of 20

The San Joaquin River Valley Project represents a comprehensive long term effort to restore the flow of the San Joaquin River. After reading the article, “River Plan Too Fishy for my Taste Buds” by Bill McEwen I chose and decided to use this article because it has plenty of reasonable facts. Bill McEwen emerged as veteran journalist who has worked in various positions for the Bee since 1980. He grew up in the community and knows how everything works. The article McEwen wrote operated and published in the Fresno Bee in March 6, 2015 in a city surrounded by farms. Fresno offers big anti business and government since the surroundings consist of mostly farms. Low and middle class people promote the highest population, meaning that they read from

The Colorado River is a very important water source for the Southwest and its people. But I think the river is most important for the farmers.

In summary, there are many different factors that contribute to the health of the Susquehanna River. The factors include the pH, temperature, phosphate, nitrate and dissolved oxygen levels. Another factor is the wildlife living in and around the water. A healthy pH level is from five to eight. The tested level was within this range! The temperature was also at a good level because it was cold enough to have the healthy level of dissolved oxygen. The dissolved oxygen level was about nine. The nitrate levels were excellent, but the phosphate levels were just good because they were slightly above where they are supposed to be. Also, by analyzing the types of macroinvertebrates in the river, the level of pollution can be evaluated. The

River, land and natural resources are important parts for people’s daily lives, and its configurations represent how people affected the environment over 150 years. With the improvement of technology, people are able to utilize these technologies to remold the river levee; however, the impacts that came from people also brought some significant changes to the area.

3. The spectrophotometer was set at 420nm. Distilled water was also used as the ‘blank’.

A river basin is an area of land that water flows across or under to make it’s way to a river. Just like a bathtub, it catches all the water that falls within its sides, and its sends all falling water to a central river or to its estuary. It drains all of the land around a major river. There basins can be divided into watersheds, or areas of land around a smaller river, stream, or lake. North Carolina is made up of many watershed that are connected to each other. In each watershed, all water flows to lowest point, to a stream, lake, river, or ocean. Everyone lives in a river basin and the actions you perform could help or harm the water quality of the river basin. You have an ecological address, and you can change what

From the Rocky Mountain National Park to the mouth at the Sea of Cortez, the Colorado river supplies water for more than 35 million people in seven U.S. states: Colorado, California, Wyoming, Utah, Arizona, Nevada, and New Mexico. Both U.S. and American citizens depend on this river for freshwater for domestic, industrial (energy), and agricultural needs—in recent decades, the fishing industry in the area has been especially depressed as water has been used to irrigate more than 5 million acres of agricultural land in the West. Similarly, dozens of dams along the Colorado River store water and generate hydropower for millions of people. Moreover, eleven national parks lie within the watershed, and the species that once thrived in the Colorado River Delta and riparian corridor–particularly birds, fish, and plants–are severely endangered. Additionally, the lands of at least 22 Native American tribes also lie on and rely on the watershed. Outdoor recreators and conservationists are of course also affected by the poor health of the river.

It is particularly important with this lab to be sure that the titration is carried out very carefully to avoid
