Acid Rain Effects
Introduction
Acid rain is rain that is acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by the emissions of sulfur dioxide and nitrogen oxide, that react with the water molecules in the atmosphere to produce acids. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and erosion of stone statues. Acid Rain have always been a problem for many countries. Countries with increase in industrial activity like china have seen an increase of acid rain.

2. Concept
"Acid rain" is a popular term referring to the deposition of wet (rain, snow, sleet, fog, cloudwater, and dew) and dry (acidifying particles and gases) acidic components. Distilled water, once carbon dioxide is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline. "Clean" or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid according to the following reaction:
H2O (l) + CO2 (g) H2CO3 (aq) Carbonic acid then can ionize in water forming low concentrations of hydronium and carbonate ions: H2O (l) + H2CO3 (aq)

A stream with a great abundance of life will probably have a reading of 7 on the scale( which is near neutral). Here are the results from some of the tests.

When the pH value of body fluids is below 7.35, the condition is called acidosis, and when the pH is above 7.45, it is called alkalosis. Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces.

1063 Words | 5 PagesI organized four different tests; pH paper, alkalinity tests, the number of rocks neutralizing acid, and the number of rocks that don’t neutralize acid. The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.
Alka Seltzer Lab Report
440 Words | 2 PagesIn acidic aqueous solution, a buffer is formed by the dissociation of the acid: HA ⇄ H+ + A- Hence, when acid is added, the excess H+ reacts with the A- to form more HA, lowering the pH and minimising the effect of the addition of acid. When alkali is added, the OH- reacts with the dissociated H+ to form water, which reduces the effect of the alkali by restoring the pH to normal levels. Alka Seltzer acts as a buffer because the citrate ions in solution (C6H5O73-) are able to react with H+ when acid is added, to form citric acid, C6H8O7. This neutralises the acid, increasing the pH. The excess HCO3- ions also react with H+ to form CO2 and water, hence lowering the pH and reducing the acidity of the solution. The HCO3- ions also act as a buffer when alkali is added, because they react with OH- to create water and CO32- ions, increasing the pH and reducing the effect of the addiction of alkali.

Ever since the industrial revolution, CO2 (carbon dioxide) has increased in the earth 's atmosphere, and much has been absorbed by the oceans, which has made a very large increase in the ocean 's acidity, when carbon dioxide is absorbed into the water, it dissolves forming carbonic acid, which is a factor that take a large part in the acidity raising, because of this, according to National Geography it has been proven that marine animals are having birth defects because of this, and because of the high acidification the acid comes down on the shells (the home) of an animal and dissolves it, causing
Egg In Vinegar Lab Report
738 Words | 3 PagesCONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq)

Rainwater flows quickly into rivers during heavy rain because there is no reservation of water by plant roots as well as water catchment areas. Due to oozing in the rivers, the water flow is slowed down and become blocked. Thus, water flow interior and causes flash floods in low areas.
Compare And Contrast Vinegar Vs Baking Soda
336 Words | 2 PagesEveryone knows the simple and easy experiment of vinegar and baking soda, but do you really know how it works. This paper will not only explain what makes these two very different chemicals react, but also what materials you will need to accomplish this easy science experiment. Baking soda and vinegar are two different chemical with two very different uses, they are not really even supposed to be used for a science experiment, take vinegar for example, some individuals use vinegar for cooking. Baking soda has a very different use, it is used for bee-stings. When vinegar and baking soda are combined, the hydrogen ions in the vinegar interact with the sodium and bicarbonate in the baking soda.
How Does Acid Rain Affect Plant Growth
1186 Words | 5 PagesIntroduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.
Acid Base Neutralization Lab Report
1001 Words | 5 PagesAcids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.

1346 Words | 6 PagesStrong acids and strong bases are strong electrolytes and are assumed to ionize completely in the presence of water. Weak acids however, only ionize to a limited extend in water. Any weak or strong acids when in contact with any weak or strong alkali will start to undergo neutralization regardless of their volume. When an indicator which is present in the acid-base mixture and have experienced colour change, it indicates that the mixture is in right proportions to neutralize each other and is also known as the equivalence point.

Ocean Acidification Essay
861 Words | 4 PagesThe topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
Acid Rain Persuasive Essay
746 Words | 3 PagesSome people call it acid deposition because they say it is a more precise name due to the fact that acid rain isn’t only rain, it can fall as rain, snow, sleet, hail and anything else. Acid rain has been formed because as we release harmful gases into the atmosphere, we are lowering the pH of precipitation, creating acid rain. Acid rain can kill small organisms such as trees and fish which destroys ecosystems. Although acid rain is not known to affect humans immensely, it can however, cause health issues usually lung
CH3COOH And Naoh Lab Report
1052 Words | 5 PagesIntroduction Strong acids and strong acids both dissociate completely in water forming ions. However, strong acids donate a proton to form H3O+ along with a conjugate base and strong bases accept a proton to form OH- along with a conjugate acid. The chemical behavior of acids and bases are opposite. When they are together, their ions cancel out and form a neutral solution. In this experiment, HCl and NaOH will react to form NaOH and H2O with these two steps: The overall reaction is: Both Na+ and Cl- ions combine to form NaCl.
