Granite, red sandstone, and pea stone will be tested to see which holds up best against acid rain conditions. Samples of each material will be submerged in vinegar to simulate acid rain and their masses measured before and after 24 hours. It is hypothesized granite will deteriorate least since it is most resistant to weathering. The experiment will help recommend the best material for a new statue given the area's acid rain levels.
The presentation is all about the environment around us and its ecology which consists of acid rain as a major problem of the environment.
Discussing its causes, effects & solutions.

This is a PPT on Atmospheric Pollution. Here it decribes the 3 main types of Atmospheric Pollution: 1.Acid Rain, 2.Ozone Depletion, 3.Green House Effect.
Smog is a kind of intense air pollution, originally named for the mixture of smoke and fog in the air. Major cities around the world are experiencing the effects of air pollution.

Air pollution: its causes,effects and pollutantsMaliha Eesha
This presentation gives the complete detail of air, air pollution, air pollutants and their types, each pollutant in detail and its causes and effects, acid rain, methods of prevention,smog,acidification,indoor pollution and so on. It is a complete package and I hope it'll be helpful in school! :)
Acid rain water has a pH <5.
Acid rain does not respect political boundaries. Emissions from one country may be carried by wind to a neighbouring country.
Water Pollution
Water pollution occurs in many different forms, is produced in a variety of ways, and has a range of effects on the biological and physical environment. Consider some common examples:
A river dashing down a steep mountainside cuts into its rocky bed and carries away sand, silt, and pebbles. When the river reaches flat ground, it deposits these materials on the river bottom.
A farmer spreads herbicides, pesticides, and fertilizer on her land, knowing the increase in crop value this practice will produce. During the next rain, some of those chemicals are washed away into the nearest lake, where they remain suspended for weeks or months.
A small crack develops in an underwater pipe that carries oil from an offshore drilling rig to a holding tank on land. Crude oil seeps out of the crack and into the ocean, where marine plants and animals are exposed to its toxic effects.
Acid rain or Acid deposition penetrates deeply into the sensitive fabric of ecosystem, thereby changing the chemistry of air, water, and soil and has huge impact

halophiles are the microorganisms that capable of living under salt conditions, generally many microbes are susceptible to higher salt concentration whereas these microbes tolerate higher salinity

In this slide indicate that, unbalance of Ecosystem and suddenly change environment due to Soil , Air & Water pollution then we go to harmful dangerous condition for survival on earth of different biological agent .in condition we are how can reduce ecological pollution their monitoring and management it.
1. WHAT IS ACID RAIN?WHAT IS ACID RAIN?
• Generally, rain water has a pH value
of 5.6 because of the carbon
dioxide from air dissolved in it.
• Any rainfall has a pH value less
than 5.6 is defined as acid rain.
2.
3. • When gas pollutants e.g. sulphur
dioxide, nitrogen dioxidedissolve
in rain water, various acids are
formed.CO2 + H2O → H2CO3 (carbonic acid)
SO2 + H2O → H2SO3 (sulphorous acid)
NO2 + H2O → HNO2 (nitrous acid) +
HNO3 (nitric acid)

10. Your TaskYour Task
• Your town council is commissioning a
new statue to be displayed downtown.
You and your lab partner will conduct
an experiment to investigate the effect
of acid rain on various building
materials in order to make a
recommendation to the town council as
to the best material to use for the
statue. In your experiment, vinegar (pH
≈ 3) will simulate acid rain.
12. HypothesisHypothesis
If pea stone, red sandstone, and
granite are subjected to acid rain
(pH ≈ 3) then granite will
deteriorate the least because it is
the most resistant to weathering.
15. Control GroupControl Group
Instead of acid rain test
(submerge) the building materials
(pea stone, red sandstone, and
granite) in tap (pure) water with a
pH of ≈ 7.
16. Variables that must be kept
constant
• Same amount of time in the vinegar
(24 hours).
• same amount of vinegar (100 mL),
same mass of building material (20
g).
• same balance.
• same brand of vinegar.
• same size container/lid.
17. Procedure
• Obtain a sample of each rock and record the
mass of the sample in grams on the data table.
• Pour vinegar into each cup until the stone is
completely covered.
• Let the stone sit for 24 hours.
• Pour the vinegar out of each cup and mass the
stone.
• Record the final mass of each type of stone in
the data table.
• Subtract the original mass from the final mass of
each stone and record the data.
