What is acid rain? Acid rain is a form of deposition in which chemicals with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7,…

Acid base balance is a part of homeostasis for maintaining the pH of the body. It is necessary for the functioning of enzymes and structural integrity of proteins. In case of an unacceptably large variation in the pH of the body, the enzymes lose their normal function, the proteins get denatured, and in extreme cases, death might result. The normal pH of human blood is 7.4, the acceptable range being 7.35-7.45. In the…

Acid rain is a precipitation which falls from the atmosphere to Earth. It contains a high level of nitrous oxide and sulphur dioxide. When they ge tin contact with water they transform to acid in the atmosphere, and then this acid is carried away by the wind thousaands of miles away from where they were created. The acidity is measured with the potential hydrogen (pH) on a scale from 0-14. The pH scale is a logarythmic measure which means that every change in pH is counted in the amount times…

Effect of Acid Rain on Wisconsin Fast Plants Introduction Acid rain has become a large environmental problem around the world. This chemically potent precipitation is incredibly common in large metropolitan cities where pollution and smog are prevalent. Acid rain has been known to diminish plant growth or completely kill off populations within the contracted areas of these large cities. In addition to effecting plants, it has also been determined that the pollutants in acid rain, such as heavy…

of the Concentration of Acid in Gastric Juice Introduction Titration is a method where a solution of known concentration is used to find the concentration of an unknown solution. A standard solution is a solution of precisely known concentration. The aim of this experiment was to go over the use of pipettes, burettes, titrations and also to reinforce the concept of molarity. In this experiment, a titration was carried out using a standard solution of hydrochloric acid to establish the…

ABSTRACT: Acid mine drainage has a prominent and damaging effect on the environment. This paper outlines the environmental impact, the chemistry behind the acid generation, and methods of treatment. The objective of this paper is to educate the reader about acid mine drainage, and what can be done to reduce this pollutant. INTRODUCTION/BACKGROUND: Acid mine drainage (AMD) often occurs at abandoned mining sites. Acid generation is the result of combining certain minerals, water, and an oxidant.…

considered as acids, those with pH values greater than 7 are known to be bases, while those having pH equal to 7 is identified as neutral substances (Petrucci, 2011). Identifying its electrolytic property also helps to characterize the given solutions. Strong electrolytes, such as strong acids and bases and salts are known to fully dissociate its ions in the solution, making it a good conductor of electricity. On the other hand, the presence of weak electrolytes, such as weak acids and bases, do…

and CO2, there is a compromise of lactate acid and acid- base balance from a high intensity exercise. The factors that avoid this change in the homeostatic limits are PO2 and PCO2, and pH. Which are maintained form increase in oxygen delivery to the alveoli and CO2 exhalation from the body (King, 2018). Acid- Base balance are affected by hydrogen ions which are formed from the lost of electrons. When a molecule releases hydrogen ion it is determined as acid, and when it is bind with hydrogen ion…

Acid rain is any form of precipitation that has unusually high acidity (a pH level below 5.6) and caused by the transformation of nitrogen oxides and sulfur dioxide into secondary pollutants. pH is is a scale used that measures the acidity of liquids and ranged from 0 to 14. The lower the number, the higher acidity, or the higher concentration of hydrogen ions. 0-5 is considered acidic and as you move up to 7, this indicates the substance is neutral. The higher numbers on the scale indicate…

The Issue of Acid Rain - SHE Task Jessie Zeitz Introduction In the 21st century, the use of cars, electricity, and coal burning power stations are being used more than ever before. This is making the issue of acid rain more and more relevant to today's society. As acid rain is not talked about much in the news, many people are not informed about it. Without it being publicly addressed much, people will not know the intensity of the situation and how bad this problem is. In Australia between the…
