The Problem Of Bunker Fuel

We took the plastic cup and added the stir bar into it, then we inserted the plastic cup and the stir bar into the styrofoam cup. Next, we secured the clamp on the ring stand rod, and then added the solution calorimeter to the other end of the clamp. Following that, we took the beaker and filled it with distilled water and transferred it to the graduated cylinder. Then we poured it into the plastic cup with the stir bar in it. We turned the stir plate to number 6 and let the water stir around for 10 seconds, then we added in our first effervescent tablet and let it for about a minute or until it was fully dissolved. We added an extra tablet to every test until we reached the total number of tablets we could insert which was 5. After we were finished with each test, we washed out plastic cup, the solution calorimeter, and the stir

The burette was refilled with the diluted sodium hydroxide solution. Steps 7 and 8 were repeated 3 times without using indicator. Sodium hydroxide was added dropwisely when the burette reading was close to the final reading in trial run.

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.

1. We measured 2 mL of diluted hydrogen peroxide (the substrate), 1 mL of guaiacol (the product indicator), and 1 mL of neutral buffer (pH 7) with a syringe and disposed it into tubes 1, 2 , 4, 9, 11, and 12.

Measure 500ml of tap water in the 500cm3 beaker, then measure 5g of sodium hydrogen carbonate using the 50cm3 beaker and weight scale and place in the beaker of water, using the glass rod to dissolve it into the mixture.

The first experiment begun by filling a 600-ml beaker, almost to the top, with water. Next, a 10-ml graduated cylinder was filled to the top with water. Once water was added to the beaker and graduated cylinder, a thumb was placed over the top of the graduated cylinder. This would ensure that no water was let out and no bubbles were let into the graduated cylinder. Next, it was turned upside down and fully submerged into the beaker. Then, a U-shaped glass tube was attained. The short end of the glass tube was placed into the beaker with the tip inside of the graduated cylinder. Next, a 50-ml Erlenmeyer flask was received. After, 10-ml of substrate concentration and 10-ml of catalase/buffer solution were placed into the flask. A rubber stopper was then placed on the opening of the flask. After adding these, the flask was held at the neck and spun softly

Cut the potatoes using a cork borer approximately 5cm in length and 1cm in diameter. Using the appropriate tool cut the potatoes into cylinder form measuring the cylinders with a ruler.

Estuaries are known for being sensitive to several human activities, such as littering and building structures like dams and seawalls that affect their natural flow of freshwater. As estuaries can prevent nearby streets from flooding, they will consequently bring many of their contaminates as well (Baker), which can pose a serious issue for an estuary’s productivity and health. UFL geologist John M. Jager argues that “toxic substances and excess nutrients [from such human-made factors] contribute to fish diseases, algal blooms, and low dissolved oxygen,” all being a threat to the health of not only the estuary itself, but additionally that of its wildlife and even humans themselves.

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

The South Australian Government is considering the regulation of Bunker Fuel in Port Adelaide, but it is facing a lot of pressure from shipping companies not to do so. In the future the SA Government plans on getting more cruise ships to come to Adelaide. The Government want to know how the increased uses of Bunker Fuel in Port Adelaide will affect the climate, and nearby residents. This report, will be looking at how the use of Bunker Fuel will affect the environment around it. This report will give the SA Government an idea of why they should or should not Regulate Bunker Fuel.

Secondly, a known volume of the unknown concentration solution should be taken with the pipette and placed into the conical flask, along with a small amount of the indicator chosen.

First of all 0.25 g of NaHco3 powder is taken and poured into a beaker then water is added until it reaches 100ml. using a stirring rod the powder is dissolved in the water resulting in having 0.25% of NaHco3 solution. The solution is then poured into a measuring cylinder slowly so it won’t be more than 100cc. The plant is being held using a pipette which is filled with water at 0.98 cm3 max so it can help us see the change in volume because when bubbles are released from the plant they go all the way up to the pipette and every time they surface volume decreases because air replaces the water. The pipette itself is held by a Screw clamp on the Ring stand. The plant is submerged into the measuring cylinder which is filled with NaHco3 solution.

Remembering my school days few days back with kids; I was thrilled by remembering those sweet an sore moments. They were really best part of my life; for you all too. Anyhow, I was telling my kids about my naughtiness in class and yes, how can I forget the experience of “bunking class”. I think you all must have this experience at least once during your school days.

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.

The purpose of this lab was to use process titration to find concentration of an aqueous solution of Hcl(aq) , using KOH(aq) as the titrant.
