When we hear someone mentioning the word ÃÂAcid RainÃÂ, we can find out from the word itself what the person is talking about. The word itself tells us that acid rain is nothing but rain which is acidic in nature. To understand the effects of acid rain and how it is caused, we must first understand the difference between a normal liquid and an acid.
acid we know that when a positive ion combines with a negative ion, it forms an ionic compound. We also know that when dissolved in water (in aqueous state), all ionic compounds split into their positive and negative ions. An acid can also be classified as an ionic compound but it has one specialty. An acid is an ionic compound which contains an H + ion. This is the basic feature found in all acids. All acids give an H + ion along with any other anion in water.
Acids also have some basic properties like being sour in taste and highly corrosive in nature.
Acid RainAcid rain occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere, undergo chemical transformations and are absorbed by water droplets in clouds. The droplets then fall to earth as rain, snow, or sleet. This can increase the acidity of the soil, and affect the chemical balance of lakes and streams. Acid rain is sometimes used more generally to include all forms of acid deposition - both wet deposition, where acidic gases and particles are removed by rain or other precipitation, and dry deposition removal of gases and particles to the Earth's surface in the absence of precipitation.
Acid rain is defined as any type of precipitation with a pH that is unusually low. Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of...
