Scenario 2
City A was found to be humid all year round (with humidity levels of around 65%).
This city is surrounded by natural forests, windy air flow and frequent rainfall during
its monsoon season. As it is located far away from the city, the air pollution level is low.
i. What will happen to a steel plate if it was exposed to this atmospheric conditions?
ii. What are the four factors that affects the rate of corrosion of the steel plate in this
scenario? Discuss the factors in detail.
(c) Table 1 shows two types of drilling fluids Al and B1 and their respective properties:
PH3
deoxidiser V
high Coa Content
sulfur removal agat v
40c
PH5
dearidiser V
low co, cotent
Suffur removal agent V
Which of the two is the better drilling fluid and why? Justify your selection by
comparing and contrasting both fluids.

Scenario 1
Picture shows a agriculture field located near a
chemical factory and often encounter acid rainfall.
The field was previously used to plant corn. The
metal water pipe buried underneath the soil
corrodes.
i. Scenario 1 shows a combination of factors, discuss how a combination of pH,
microbiological activities and degree of aeration affect the rate of corrosion in the
context of this scenario.
ii. Explain how the lack of oxygen may have caused the metal water pipe buried
underneath the soil to corrode.
