    • 614 Words
    • 3 Pages

    Acid rain is a common term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce a rain‚ snow‚ or hail of sulfuric and nitric acids. Such pollution may also be suspended in a fog‚ or the pollutants may be deposited in dry form. Environmental damage from acid rain has been reported in northern Europe and North America. High levels of acid rain have also been detected in other areas of the world‚ such as above the tropical rain forest of Africa. Acid rain

    are several purposes to the amino acid lab experiment. One reason is to help us understand the concept of acids and bases and how they interact with one another. Another purpose is to understand what occurs when placed with the existence of buffers. Lastly‚ the experiment is to help us understand the applications of titrations and how it can be used in a real world setting‚ in this case‚ the identification of an amino acid. One must understand that amino acids all have special characteristics

    Acid Rain Essay

    • 1696 Words
    • 7 Pages

    Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

    Acid rain is rain that has become acidic‚ because of air pollutants in the atmosphere. Rain has a normal pH level of around 5-5.5 which is only slightly acidic. 7 on the pH scale is the neutral and anything below that is considered acidic. Acid rain has a pH level around 4 which is 10 times more acidic. Acid rain can fall in many different ways and has many effects on the environment. Acid rain is caused by air pollutants in the atmosphere. These air pollutants are mainly from man made resources

    Essential Fatty Acids (EFAs) are fats that are required by the human body‚ but cannot be made by the body; therefore they must be obtained from external forces such as food. EFAs are the building blocks of all fats and oils and are required for both metabolic processes and for fuel. EFAs form the main component in the fats carried in our blood stream (triglycerides)‚ fats stored in our bodies and of cell membranes (phospholipids).
