The Problem Of Bunker Fuel

Better Essays
Introduction:
As technology and transport becoming more convenient and advanced for the general public, one of the problems is the cost of running them, and bunker fuel is the solution but also the problem. Bunker fuel is a type of fuel which is fractionally distilled from crude oil, it’s full of impurities, and also known to be a threat to the natural environment and the human health. However, bunker fuels are still used worldwide today for commercial shipping, because of the cheap price. (wiseGEEK, 2015)
The burning of bunker fuels release sulphur dioxide (SO2) and nitrogen oxides(NOx) , which will combine to react with water(H2O), oxygen(O2) to make sulphuric acid and nitric acid. Both acids are then fused with other impurities to

This includes the Port River, the home to the only city dwelling dolphins in the world. To decide whether or not to regulate the use of bunker fuels, the government of South Australia wanted further information about any potential harmful environmental effects this has on Port Adelaide, particularly in any increased acidity in the waterways. This investigation is to carry out an experiment to test whether or not bunker fuel will have negative effects on Port Adelaide’s waterway acidity, by taking water samples from the Port Adelaide waterway, Bangladesh waterway and the Waterfall Gully waterway to compare the acidity of each. Bangladesh is exposed to a high level of bunker fuel burning, while Waterfall Gully is exposed to a low level of fuel burning. If water samples from Bangladesh are high in acidity then Port Adelaide should not regulate the use of bunker fuels.(Acid rain Design Investigation Task Sheet, 2015)
Method:
Titration-
The stand, clamp mat and a 250mL conical flask were set up as demonstrated in figure 1. A burette was rinsed with 10 ml of 1.0M NaOH(aq), and made sure the end of the burette and the flask were about 5cm away. Checked the stopcock of the burette and made sure it was shut, then a funnel as used to fill the burette with 0.1M NaOH(aq) until the reading is between 0 and 1mL. This was recorded as initial value. A 20ml pipette was rinsed with 5mL of HCI, and then the 20mL of HCI was transferred to the conical flask using the pipette. 5 drops
