Arrhenius Theory The Arrhenius theory of acids and bases was initially suggested by the Swedish chemist Svante Arrhenius in 1884. He recommended classifying specific compounds as acids or bases based on what kind of ions made when the compound was added to water. Arrhenius Acid Any species that rises the protons and concentration H(+) ions in aqueous solution called Arrhenius acid. For example, the dissociation reaction of HCl in water:
A. Acids and Bases Acids are a material that releases a proton or hydrogen ion (H+). Acids always generate an H+ whenever the solution is aqueous, which can be easily identified. On the contrary, in an aqueous solution involving bases always produce an OH- ion. There are many different ways to identify whether a substance is an acid or a base. An acid is always sour, changes litmus, conduct an electric current, react with a base to form salt and water, and whenever there is a reaction, acids
global climate changes, and even the melting the polar ice caps. This has now caused the ocean water levels to rise, which has, in turn, started to cause even more troubles.

Fossil fuels have done so much for us in the past but the question still remains; what do we do when the planet runs out. Along
Climate change is arguably one of the most controversial topics in modern science, and undoubtedly one of the most important. Ongoing research has shown that the planet’s climatic temperature has increased slightly yet significantly over the past century. Studies have also found that this warming can be attributed to human activities since the Industrial Revolution in the eighteenth and nineteenth centuries. As time goes on and humans continue their harmful actions, climate change and its related
atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution. According to S.M. Enzler MSc from the article History of greenhouse effect and global warming, Svante Arrhenius was a Swedish scientist that was the first to claim in 1896 that fossil fuel combustion may eventually result in enhanced global warming. Global Warming have gotten worse since the first record keeping in 1880. According to Peter M. Vitousek
Temperature's effect on Chemiluminescence Sitting by a fire on a fall night one would not think of a campfire as cold light. Could there be such a thing? “Cold light” is what the word luminescence means (Fluorescent Mineral Society, 1 of 2). Cold light can be seen at many different temperatures. Not only does cold light exist, but there are several types of luminescence including bioluminescence or “living light”, photoluminescence or fluorescence, “day-glow”, and phosphorescence which is
INTRODUCTION OF ACID BASE REACTION Acids and bases play a essential role in chemistry because, with the exclusion of redox reactions, each chemical reaction can be categorized as an acid-base reaction. Practical use of acid base chemistry Acid-base chemistry is central to us on a practical level as well, outside of laboratory chemical reactions. Our bodily functions, going from the microscopic transport of ions through nerve cell membranes to the macroscopic acidic digestion of food in the stomach
the Swedish chemist Svante Arrhenius theorized compounds would be classified into two different substances. These two substances are acids and bases. The Arrhenius Theory of acids and bases states that acids are substances that dissociate to form charged atoms known as ions. Bases ionize to produce hydroxide ions while acids produce hydrogen ions. HCl is an example of an Arrhenius acid because it dissociate into an H+ ion. The reaction involving NaOH is an example of an Arrhenius base because it is

Svante Arrhenius, although not a member of the Nobel Committee for Chemistry, had a great deal of influence in the Academy and also pressed for the rejection of Mendeleev, arguing that the periodic system was too old to acknowledge its discovery in 1906. According to the contemporaries, Arrhenius was motivated by the grudge he held against Mendeleev for his critique of Arrhenius's dissociation theory
The Primordial Soup Theory The primordial Soup theory was discovered in 1920. According to the Russian scientist A.I. Oparin and English Geneticist J.B.S. Haldane life started in a warm pond/ocean in a process that took place 3.8 billion years ago. A combination of chemicals made fatty acids which made protein. In this process a molecule was born in the atmosphere. The molecule was energized with lightning and rain making “organic soup”. The first organisms would have to be simple heterotrophs
Introduction The world we live in is full of chemicals and elements, we just do not simply notice them. In Everyday life there are acids, bases, and salts. Some may not know how to see them or even what they are. You might put baking soda into vinegar to see what happens afterward. We put salts on our food to make it taste better. There is salt in every ocean on earth. There are so many acids, bases, and salts around us and we just do not see them. We eat a neutralizer when we get heartburn
So in 1861 a physicist names John Tyndall showed how water vapor and other gases create the greenhouse effect. Then in 1896 a chemist named Svante Arrhenius says that industrial age coal burning will enhance the natural greenhouse effect. He then goes onto say that it might benefit future generations. So then in 1900 Knut Angstrom discovers that even the tiny concentrations found in the atmosphere
Climate change, is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. These times can be anywhere from decades to millions of years. The Earth’s climate has constantly been changing throughout history. Climate change can be dated back to over 650,000 years ago. Most of the changes that happened before 7,000 years ago happened because of small variations in Earth’s orbit that change the amount of solar energy the earth planet receives
Arrhenius estimated using the greenhouse gas effect theory, that if the total amount of the carbon dioxide concentration in the atmosphere were cut in half the surface temperature of the Earth would decrease and if the opposite occurred and the carbon dioxide
the types of ions the substance contains. Due to how wide the range is from a very acidic solution to a very basic solution scientists created a scale, the pH scale, to measure how acidic or basic a substance is more easily. A Swedish chemist Svante Arrhenius came up with the theory of how to tell the difference between a base and an acid in 1887. His experiments illustrated that if you put molecules in water they would either release a hydrogen ion or a hydroxide ion. A compound that releases hydrogen
today as we strive to control its damaging effects on the biome system. While some groups blame human behavior for this devastating problem the effects of nature also have its fair share. The beginning of climate change science can be traced to Svante Arrhenius, a Swedish scientist who concluded in his 1896 study that changes in of carbon dioxide or CO2 could produce effects on the climate. Later, in 1938, Guy Stewart. Callendar, an English engineer, asserted that the increased CO2 levels
The antacids contain a mixture of weak bases such as magnesium hydroxide Mg(OH)2, aluminum hydroxide Al(OH)3, and calcium carbonate CaCO3.The weak base in the antacid neutralizes the hydrochloric acid and relieves heart burn.4 According to Svante Arrhenius an acid is a substance that produces hydronium ions (H+) and a base is a substance
be explained as a long series of events, mostly in response to the international attention given it. The idea that excess carbon dioxide in the atmosphere could trap heat in Earth's atmosphere was first put forward in 1898 by Swedish physicist Svante Arrhenius. But it wasn't until the late 50s that scientists within U.S. federal agencies started to participate in scientific workshops, international conferences, and international scientific research that explored the nature of Earth?s climate system
The worldwide increase in temperature and the resulting climate change, known as Global Warming, could be a threat to the environment and have serious negative effects on all living things, including humans. Scientists agree that the temperatures on Earth are rising, but an agreement on what is causing it has not been reached yet, and how the government should address the problem is still being discussed. The debate is between who consider the climate change in the last century a completely natural
Half of the United States population traveled out side of the borders in 2012. Ten present of the population traveled to the Carrabin in 2012 (United States). Traveling is a way of life for some and a major influence on the United States culture. Despite the recent recession traveling has increased in popularity among Americans. Some believe the increase in popularity for traveling is a result of global climate change. Global climate change refers to the natural change in global temperatures over
