Acid Rain And Bunker Fuels Investigation

pH was recorded every time 1.00 mL of NaOH was added to beaker. When the amount of NaOH added to the beaker was about 5.00 mL away from the expected end point, NaOH was added very slowly. Approximately 0.20 mL of NaOH was added until the pH made a jump. The pH was recorded until it reached ~12. This was repeated two more times. The pKa of each trial are determined using the graphs made on excel.

In 2 and 7 I added 50 mL of .1 M NaCl. I added sodium acetate to the rest of the beakers: 1 gram to 3 and 8, 5 grams to 4 and 9, and 10 grams to 5 and 10. I then filled the beakers that contained the solid sodium acetate with 50 ml of .10 M acetic acid. Specifics can be found on page 84 of the lab manual. Though the lab manual instructed to use a pipet, we did not have an accurate 1 mL pipet or a graduated pipet, so we instead prepared two graduated burets with 1 M Sodium Hydroxide and 1 M hydrochloric acid. Using a standardized pH probe with a Lab Pro to measure changes in pH, we added 1 mL of HCl at a time and recorded the changes. The same was done for the NaOH.

“The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity (sic) of the solution. The letters pH stand for power of hydrogen and the numerical value defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.” (PH, 2002). The pH scale is from 0 to 14. When the pH is higher, the hydrogen ions are fewer and the substance considered alkaline. This means when a pH unit increases by one, there is a tenfold change in the hydrogen ion. For example, if a substance has a 7 pH, it has 10 times as many as hydrogen ions available as 8 pH. A lake having a water pH between 6.5 and 8.5 is considered to be neutral. Researchers tested Peckham Park lake water monthly from August 2015 to April 2016 for water pH levels. A water quality PH test strip taken from a jar and dipped into the lake. After a few minutes, the strip will turn a color and this color determines the pH. The jar the strips came in has a chart of the colors on the back which compared to the color on the strip. The lake tested monthly using the PH test strips, which show the pH level, hardness, toxic, etc. using color-change

ii. The second part of the titration series involves titration of NaOH with Hydrochloric acid (HCL). Again, three reps of titration and a blank titration have to be completed. A volumetric pipet is used to measure 10.00mL of HCL into three labeled conical flasks. Then the flasks are filled with deionized water until about the 50mL mark. A buret is

To improve the results from the experiment buffer solutions that were not whole pHs could have been used e.g. pH 4.5, 5.5 etc. This would have provided more reliable results as a wider range of results would have been produced. Using pHs with decimals would also help to more accurately determine the optimum pH as the optimum may have been above or below the pH stated in the hypothesis; 8. In this experiment however the optimum is taken at 8 because the graph does not rise again.

The most prominent geologic feature of the upper Texas coast is the Galveston Bay, covering to the extent of within 600 square miles, it's one of the most urbanized and industrialized areas. Just like any other chill evening in the Galveston Bay, TX everything was calm as air, but on March 22, 2014 after a dramatic collision between a ship and an oil barge. Opproximatley more than 150,000 gallons of fuel oil so heavy it wont evaporate as easy and it'll also be difficult to clean up. It quickly leaked into the Houston Ship Channel, and started to expand on / upon nearby marshes. This chaotic spill unleashed, as much as 168,000 gallons of bunker fuel, a thick, cheap fuel that powers big ships. In the past their has / had been many calls to ban banker fuel. Furthermore, within days of the spill, the disperse of the bunker fuel was evident. Oil was detected not too far in the Gulf of Mexico 12 miles offshore on a crisp Sunday, March 23, and

We will begin by preparing the pH standards using 16x125 mm test tubes being sure to add 5 drops of Bromothymol blue and then mix thoroughly. Into six additional test tubes we will pipette 10ml of each of the following (one in each tube): prepared buffer, 0.1M sodium acetate, 0.1M NH4Cl, distilled water, unknown, and unknown. Be sure to thoroughly mix the 5 drops of Bromothymol blue in each. Finally, estimate and determine the pH of the solutions.

Wrigley Field There is no place more exciting then Wrigley Field, home of the Chicago Cubs. The crack of the bat brings a shivering chill down your spine, the intimacy of the crowd and the player’s shows a sensational bond of loyalty, and the spectacular defensive plays made on the field makes every dollar spent worthwhile. The booming sound of a bat crushing a ninety five mile per hour fastball is one of the most satisfying sounds heard in the game of baseball. It brings the crowd to their feet and quickly sends an electrifying pulse of energy up and down through the stands.

Abstract: During this lab, the pH of water in soil from a man made garden, a deciduous forest, and a river bank were tested after leaving it in containers for one, two, and three hours, coming out to a total of three trials with three different soils all together. After testing the pH of the water when being added to the soil for the desired amount of time and comparing it to the original water with no soil added, is then when each pH difference was observed and recorded in a a notebook, while pictures were taken of the experiment being conducted.

In this project, parameters such as turbidity, COD, BOD, TSS and pH were measured where turbidity was measured according to the turbidity meter (2100N, HACH, USA) procedure meanwhile pH was measured according to pH meter (Crison pH 25) procedure. 3.8.1

Despite the Acid Rock Drainage being a good thing, it can lead to some horrible things for the ecosystem if it isn’t used submissively. For quite a while, Britannia Mine didn’t have Acid Mine Drainage under control. Britannia Mine was founded in 1900 in British Columbia and it closed down in 1974. Acid Mine Drainage was executing the ocean life beside Britannia Mine, Howe Sound. The acidic water was leaking from the mine and found its way into Howe Sound, making the water lethal to all the sea animals. For years upon years, there were no fish in that one section and in the early 20th century the problem was helped by the government and a few years later, a water purifier was created which has now made it so that the Howe Sound sea life grows. A lime and water concoction gets put into a tank, which has the Acid Rock Drainage matter, which brings the pH level to 9.3 after being at nearly 4. A polymer gets added which sinks all the metal and the water gets drained out. It’s then taken to a purifying tank and the waste is then put at the top of the

When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best results when testing the pH within a solution. The pH, which stands for the proportion of hydrogen ions in a solution, could be acidic (acidosis), neutral or basic (alkaline). The pH scale goes from numbers 1 through 14. A pH of 7 is neutral;

The purpose of this investigation was to answer the question was to the report will be on the expected impact of increased bunker fuel emissions on the acidity of the local waterways in Port Adelaide. The aim is to find that the use of bunker fuel in unrestricted areas will generally cause a decrease in the pH level of water, therefore making it more acidic. Experimental tests of pH and Titration will be taken, and recommendations about whether SA should regulate the use of bunker fuel in Port Adelaide will be provided.

Sodium hydroxide solution was run from the burette into the flask with the magnetic stirrer being turned on. When the indicator was turned slightly yellowish, sodium hydroxide was added dropwisely until the reading of the pH meter is 7.00. The final burette reading, accurate to the nearest 0.05cm3, was recorded.

In this lab a acid-base indicator phenolphthalein was used to determine endpoint of a reaction HCl(aq) and KOH(aq). At the end point all of the HCl(aq) would have reacted with KOH(aq), and the pH becomes 7. The phenolphthalein would changed colours from colourless to pink indication when enough KOH(aq) was added. The purpose of numerous trials was to use the average volume of the 3 trials with similar measurements.
