Acid In Waterways Lab Report
Introduction
Bunker fuel has been used in boats for a number of years now however it has only recently bee discovered that the fuel could actually be harming our waterways. When there is excessive amounts of bunker fuel in a waterway it can acidify the water. This means that when the waterway goes through it’s hydrological cycle (figure 1) and the water evaporates into the atmosphere and returns in
(Water Cycle, 2012) rain form it creates acid rain. When acid rain occurs in an area for a prolonged amount of time it can have dire effects on the environment such as; lack of nutrients in the soil and in the waterways, it kills the surrounding trees and it can also poison the fish (Nelson Tulane, S, n.d.). To test if our local waterways are too acidic due to bunker fuel water samples from Waterfall Gully, Port River and Johnstons Creek. These will then be tested with the pH scale to find out the results.

After heading up to the lab 12 x 250ml beakers were grabbed as well as; a glass stirring rod, universal indicator, a pH scale, a pH probe and 200ml of each water sample. 50ml of each sample was poured into the twelve separate beakers with five drops of universal indicator which was stirred in with the glass stirrer. Once the water had settled to a singular colour it was compared to the pH scale which showed how acidic the water is. This was done with all 12 beakers. Then, the pH probe was grabbed and used in each of the 12 beakers to
What Is The Chemistry Of Natural Waters Lab Report
528 Words | 3 PagesThe procedure for this experiment is found in Stephen Thompson’s PSU Chemtrek on p. 10-15 through 10-22 under the “Chemistry of Natural Waters” lab. For the testing, four tap water samples were obtained from Virginia and State College, Pennsylvania—McDonald’s, the Atherton Hotel, and McKee Hall. Each member of the group proceeded through the testing methods in order to determine the hardness for a particular water sample. In accordance with the procedure, the AA technique was used first. Because the water sample from McKee Hall had no suspended particles, no filtration was required prior to testing; however, the sample was diluted with a 1:1 ratio.
Congregated Salmon Lab Report
1799 Words | 8 PagesOne test conducted was the measure of nitrate in the water. If there is too much nitrate it grows algae which is then eaten by bacteria, and can cause Eutrophication. Another test was done to determine the amount of BOD, which shows how much dissolved oxygen is needed by Aerobic bacteria in order to break down material. Ph is responsible for how acidic or basic the water is. If a body of water has a high ph it can be unsuitable for aquatic life.
Susquehanna River Lab
627 Words | 3 PagesTo do the temperature and dissolved oxygen tests, stick the probe in the water, and it will show numbers. One will be the dissolved oxygen in ppm (parts per million) and the other will be the temperature of the water. To do the pH test, stick the pH paper in the water and compare the color it turns to the scale. To test nitrates, put clear water in a container and dirty water in another, and put powder in them. Shake them and then compare the color they turn to the scale.
Unknown Weak Acid Lab Report
1111 Words | 5 PagesA 0.2057 M stock solution of NaOH was added to the plastic syringe while the acidic solution was being made. 1.329 g of unknown acid P was weighed on the electronic scale and recorded. The unknown solid acid was placed into a 100 mL volumetric flask and filled to the line with a 0.1 M stock solution of KCl. The solution was agitated to aid in the dissolving of the solid acid solution. When the acid was completely dissolved 25 mL of distilled water was added to a clean 100 mL beaker, along with 25.00 mL of acidic solution using a volumetric pipette.

Beaker Observations 1 There was no smell 2 When I pour the oil in the water I noticed the oil started to bubble to the top. So I got to stir the oil that’s when there were smaller bubbles. As I smell the water there was no smell to the water.

1184 Words | 5 PagesIf there is a color change, then it is known that protein is present in the solution. Finally, lipids are tested. 5 mL of water are added to 5 mL of oil. 5 drops of Sudan 3 are added, and if the color changes, then lipids are present. Next, the McMush is tested.
Conodoguinet Creek Research Paper
1063 Words | 5 PagesI organized four different tests; pH paper, alkalinity tests, the number of rocks neutralizing acid, and the number of rocks that don’t neutralize acid. The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.
Research Paper On Ocean Acidification
731 Words | 3 PagesOcean Acidification is a pressing issue that will have a major effect on the ocean in the near future. According to the National Oceanic and Atmospheric Administration (NOAA), ocean acidification is when the pH drops due to an uptake of atmospheric carbon dioxide. This is a controversial issue because many people do not believe the ocean is becoming acidic. They believe ocean acidification is a hoax brought on by global warming to try and convince people on the dangers of climate change. This issue is important because ocean acidification posses a threat on the coral reef ecosystems, which house 25% of marine, fish species.
Ocean Acidification Lab Report
898 Words | 4 PagesOcean Acidification Lab Dyana Padron Chemistry Ms Johnson June 1st 2015 Introduction: Ocean acidification is when the ocean 's pH is downsized. Ever since the industrial revolution, CO2 (carbon dioxide) has increased in the earth 's atmosphere, and much has been absorbed by the oceans, which has made a very large increase in the ocean 's acidity, when carbon dioxide is absorbed into the water, it dissolves forming carbonic acid, which is a factor that take a large part in the acidity raising, because of this, according to National Geography it has been proven that marine animals are having birth defects because of this, and because of the high acidification the acid comes down on the shells (the home) of an animal and dissolves it, causing
Research Paper On Ocean Acidification
372 Words | 2 PagesOne of the biggest problems on our planet at the moment is the 79 million tons of carbon dioxide being released into our atmosphere every day. According to the European Project on Ocean Acidification, one third of all the Co2 that has been released into our atmosphere has been absorbed by the world 's oceans. Without the immense size of our oceans absorbing all this CO2, our atmosphere would suffer from extreme global warming with devastating effects. However, the downside of our oceans absorbing most of the CO2 is that it threatens the health of our oceans and the animals inside it. It all starts off when the CO2 from the atmosphere is dissolved into the oceans.

Acid Base Neutralization Lab Report
1001 Words | 5 PagesAcids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.

Ocean Acidification Essay
861 Words | 4 PagesThe topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
