What is acid rain? \nWhat causes it? \nWhat can be done to decrease it?
203872
Acid rain is any type of precipitation with a pH that is unusually low.\nIt occurs when sulphur dioxide and nitrogen oxides emitted into the atmosphere undergo chemical transformations and are absored by the water droplets in the clouds.\nThe only way to decrease it is to reduce the amount of suphur dioxide and nitrogen oxides emitted into the air, for example, coal-burning power plants can use Flu gues desulfurization to remove sulfur containin gases. lime or limestone in slurry form can be injected into the reaction tower to mix with the stack gases and combine with the sulphur dioxide present.\n\nhope this would help!

Air pollution is any substance that is emitted into the air that hamrs the environment. Preventive measures include finding newer energy sources, using less of the energy resources we have, driving less, and cleaning the emissions fron factories better than we are. Its effects on humans and plants include respitory problems, growth stunting, cancer of the skin, and prolonged exposure can include death and loss of sight and other motor skills. Thats all I have time to give you.

Acid rain is formed by the oxidation of sulfur and nitrogen containing compounds which have emissions of both natural and human origin. This oxidation occurs in both the gas phase and in raindrops to produce sulfuric acid and nitric acid.

You usually use hydroponics, i.e. you add salts of different essential macr and micro nutrients like iron oxide and potassium nitrate and add some EDTA to stop precipitation. But if yours is a low level experiment, try different types of soil --clay, sand and loam, and add in different amounts of water, maintain in diff. temp. and lighting.

The pH of acid rain can be anything less than the pH of normal rain, which actually tends to be around 5-6 (rather than 7 as you might expect).  There's no magic pH at which it becomes acid rain; it just depends on how much acid is around.  Sometimes the pH can be as low as 2, or even 1, other times it will be more like 3 or 4, it really just depends how much pollution there is.  If you want us to find the concentration of H+ in the acid rain, you have to tell us what pH you're thinking of!\n\nAs for the coffee thing, you should be able to figure that out yourself for any given pH using the formula pH = -log[H+] and solving for [H+].

Rainwater will have a pH determined by its composition.  Its composition will be water (pH=7), O2, CO2, SO2, NOx,... stop me when I've mentioned something that strikes you as a product of human pollution.  There are some ultra left wing radical commie pinko pseudo scientists who LIE about pollution and say it is a GLOBAL problem.  But WE all know that we can fowl our rivers and burn our forests and nothing will be affected more than oh a couple of feet away, right?  RIGHT?!! Tha tha thats all folks.

Lacking more detail - my suspicion is that the release of H2 will cause the amount of aluminium to be to high...\n\n-dh

We in India have the study of acid rain in our curriculum. And the example cited is that of the Taj Mahal. This massive structure, now in the race for the new 7 Wonders of the World, is entirely made from marble(Calcium Carbonate). The oil refineries from nearby towns release sulfur dioxide in the air which comes down as acid rain. \n       You know how sulfuric acid and marble react. This is causing etching or pitting of the marble(formation of tiny holes), damaging the monument. People complain that the Taj is not as white as it originally was.

Of course its bad... I mean it harms our lungs and it has carbon monoxide which can kill us by taking oxygen.\n\nAir pollution also causes Acid Rain and it harms the Ozone Layer. So with Air Pollution our lovely Earth's being destroyed.

Problem State: \n68 million acres of forest damaged or destroyed by acid rain \n\nAcid rain is caused primarily by the emission of sulfur dioxide from coal-fired power plants. There are a number of remedies, including: switching fuel sources to natural gas, oil, or renewable energy sources; switching to low-sulfur coal; removing the sulfur from the coal before burning; using fluidized-bed combustion processes to burn the coal; and removing the sulfur from the smoke stack after combustion through the installation of pollution control equipment such as "scrubbers." \n\nCosts/Benefits \n\nA combination of tax incentives, government regulations and direct assistance that results in pollution-control equipment being placed on all coal combustion sites, increases in efficiency of industrial processes, transportation and appliances would cost approximately $8 billion per year for ten years. This is about 1% of the world's total military expenditures.

I have never heard of this happening. You should go to your regular dr., who can refer you to a specialist, if needed. I have heard of people being able to tell if it is going to rain due to their arthitis flaring-up and if they get a headache. Something about the barametic pressure. I believe that it would be well worth it for you to find out exactly why this happens to you. Good Luck!

Rainfall makes the salinity of the bay decrease.  Since there is no salt in rain it makes sense that by adding water to salt water the salinity will decrease.

yeah that sounds like gastric ulcer this means that there has been a  puncture created by acid from ur stomach cells in ur stomach. this is going to allow the acid whiich has a pH of abt 2 to trickle little by little in the space and affect other organs causing irritaions. better see a doc quick.

well I think no. because dilute HCl has a low concentration therefore it produces less hydrogen ions. so the less hydrogen ions it produces the less pH  it has

Pollution can cause the following harms:\n1. Dust particles and smoke particles deposit themselves in the lungs and cause respiratory problems.\n2. Carbon monoxide react with the red blood cells to form carboxy haemoglobin. Then red blood cells loose the capacity to carry oxygen.\n3. Chlorofluorocarbons destroy the ozone layer and this in turn can cause skin cancer.\n4. Sulphur dioxide and nitric oxide dissolve in water to form acid rain. This acid rain destroys buildings and damages crops and trees.\n\nWell,that's all i have.Hope this bit of information helps you to get through your homework.\nAll the best.

Add dilute hydrochloric acid. If you see fizzing, it's the carbonate!
