Abstract
Acid Rain has a lot of effects on living organisms and on the environment. This experiment has two purposes. One is to determine the acidity of rainwater in certain areas in the Philippines. Another purpose is to determine which type of area-urban or rural- is more subjected to acid rain. The experiment was done by first collecting rainwater from selected rural and urban areas. After the collection was done, the rainwater samples were tested using a pH meter. The results of the pH test of rainwater in urban areas: in Novaliches, Quezon City, in Philcoa, Quezon City, in Katipunan, Quezon City, in Paco, Manila, and in Malate, Manila are between 6.08 to 6.10 The result of the pH test of rainwater in rural areas: in Iriga City, Bicol, in Buhi, Bicol, in Naga City, Bicol, in Calamba, Laguna, and in Biñan, Laguna are between 5.7 and 5.8. There are different aspects that affected the results; these aspects will be further discussed in the Review of Related Literature part of Chapter I. The results gathered were treated statistically using T-test to compare the pH level of the rain from urban areas and rural areas. From there, the researchers concluded that rainwater from rural areas is more acidic than the rain from urban areas. It is because rural areas are unpolluted while urban areas are drastically polluted.

This research can help the people interested to know the acidity of rain from urban areas and rural areas. This can serve as their basis for further studies.

CHAPTER I: INTRODUCTION
Background of the study
Along with the growth of industry is the increase in pollution. Air pollution is one of the most pressing environmental issues today. Its impact on humans and the environment is great. Climate, particularly rain, is also considerably affected by air pollution.

Acid rain is one of the effects of air pollution. It is formed due to the increased number of air pollutants that mix with the atmosphere. The amount of pollutants present in the atmosphere greatly affects the rain especially its pH level, which makes it less acidic or more acidic depending on how much pollutants are there in the atmosphere. Although the effects of acid rain are inconspicuous at first glance, it actually affects the surroundings due to the damage it brings. The consequence of acid rain is evident in man-made structures and natural surroundings. It corrodes paints, metals, and monuments and it also brings problems to farmers as it seeps in the soil which causes it to lose the nutrients plants need to grow.

The researchers would like to conduct their own experiment to find out the acidity of rain in certain parts of...
