Nitric acid

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,…

electrolytes in their cell structures. In humans this balance is regulated by hormones. Disruption of this balance leads to health problems. Electrolytes are useful for electrical batteries and fuel cells. Electrolytes commonly exist as solutions of acids, bases, or salts. Some gases act as electrolytes under conditions of high temperature of low pressure. Solutions are formed when a salt is placed into a solvent such as water. An electrolyte solution may be described as concentrated if it has a…

testing various concentrations of nitric acid in different samples of cyanobacteria of equal masses. My hypothesis is that acid rain will greatly affect the growth of cyanobacteria. The higher the acidity level of the water, the less the cyanobacteria will grow. I chose this topic because due to human activities, many different chemicals have been released into the air and they changed the mixture of gases in our atmosphere, hence resulting in a dramatic increase of acid rain levels.…

Acid rain is a rain that is more acidic (has more hydrogen ions) compared to normal rain and it has serious negative effects to nature and people. It is a mixture of wet and dry depositon that contain high amounts of nitric and sulfuric acids (see Figure 1). These gases come from electric generation, factories, forest fires, burning fossil fuels and acid rain forms when these gases react with water, oxygen and air. Wet deposition happens when acid chemicals fall to the ground in a rain or snow…

Acid rain is any form of precipitation that is extremely acidic, causing harmful effects on the environment. The unusual acidity of acid rain is caused by the high levels of nitric and sulfuric acids in the atmosphere, generated mostly by human activities but also by natural activities. This document will describe the process of acid rain from creation to the effects it has on the environment. Chemical Sources In the formation of acid rain, natural and human-made sources are known to play a…

different concentrations of nitric acid (measured in molars) with copper powder (grams) affect the rate of reaction (measured in seconds) measured using a stopwatch? Hypothesis: The copper powder placed in the most concentrated amount of nitric acid, measured in molar, will take the least amount of time, measured in seconds, to react compared to the amounts of copper powder in other less concentrated amounts of nitric acid. This is as if the concentration of nitric acid is increased, then the…

nitrobenzoate even if it has little different melting point from the literature melting point which is 7880°C. Conclusion/Discussion: During the electrophilic aromatic substitution reaction between methyl benzoate and a nitrating solution of sulfuric and nitric acids, the Meta-Methyl nitrobenzoate product was obtained based on the product melting point range. Percent yield of the crude 56.42% and the percent yield of the recrystallized product was 52.59%. This would indicate that during the…

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…

prevailing winds and can travel long distances to other regions or locations where they can also cause great damage. The pollutants react with water (H2O), oxygen (O2), other gases and sunlight to form sulphuric acid (H2SO4), ammonium nitrate, and nitric acid (HNO3) (Dubey, 2013; ESA,…

strong acid. Then, react one of the unknown solution with all of the others and note any visible reaction (change in color or formation of precipitate) that occurs. After that, some the solutions might be identified throughout the…
