1a) Coal plants release huge amounts of water vapor during the combustion process of the coal. Water vapour when cooled becomes visible as fog.
1b) pH of rainfall in the park is pH 6 as the pH scale is logarithmic.

4) Acid deposition is problematic especially in the region of eastern Canada because waters and soils in those region lacks natural alkalinity and therefore cannot neutralize acid naturally. Canada has since cap Sulfur Dioxide to 2.3 million tonnes in the seven eastern most provinces and has also negotiated with the United States to cut sulfur and and nitrogen oxides emission. In Singapore, acid rain is generally not a concern due to the good air quality that Singapore enjoys. However, acid rain may be more of a concern during the hazy seasons. The haze problem in Singapore normally originates from Indonesia as the government are incapable of monitoring their own citizens to prevent them from illegally adopting the slash and burn practices thereby causing air problems to countries all around them. Therefore we can say that the acid deposition originate, if any, originates from outside of Singapore.
