Calcium hydroxide

Many of us would like to understand what Arsenic is and why this element is in our drinking water. To begin with our introduction to Arsenic, we should all understand that it is a semi-metal element from the periodic table that we are mostly familiar with. It is odorless and has no type of specific taste to the human tongue. It is mostly sourced from natural deposits in the Earth, however, it’s also known to be sourced from agricultural and industrial practices all over the world. It is simply…

separate the liquid. 10-ml of 3 M aqueous sodium hydroxide solution is added to the distillate. Furthermore, the mixture is shaken until two separate layers of liquids are observed. On the top was the organic layer and bottom the aqueous layer. The aqueous layer is discarded while, the organic layer is kept, which will produce our products for this experiment. The organic layer then is transferred to a dry 50-ml Erlenmeyer flask and then dried with calcium chloride. The mixture is…

Introduction In order to construct and completely understand the significance of the materials necessary to build a robust bridge, multivariate factors need to be deduced. These include; the location, the material of the steel and the characteristics of the cement mixture. Of the aforementioned factors, location is significant in informing Material Engineers regarding the type of environment in which the structure is built. The environment thus plays a pivotal role and governs the formation of…

Discussion of Results: This experiment consists of three different parts. The main goal of the experiment is to identify the unknown compound the lab group was given. Along with this, the group is to discover the compounds many physical or chemical properties. Lastly, the group is supposed to create and preform two syntheses of the compound and see how they compare and contrast in different areas like costs effectiveness, safety, and potential yield of the compound. Through all of these…

quickly distributes to all organs and tissues. After about a month, our body eliminates it. The health hazard of the radiation causing cancer is about 0.004 percent. In 1.28 billion years, 89 percent of the time, half of the potassium 40 decays to calcium-40 by emitting a beta particle, while 11% of the time it decays to the gas, Argon-40, by electron capture. Besides radiometric dating, there are no specific commercial or medical uses associated with the radioactive properties of potassium-40.…

The bones in our body are formed mainly by salts of Calcium (Ca) and Phosphorous (P) and are the structural components that keep our body sturdy and gives us our shape. Bones are very strong solid materials in which its molecules are very close together but have little to no movement. Our body also has its…

3. SAFETY AND ENVIRONMENTAL ASPECTS OF SULPHURIC ACID PRODUCTION 1. Safety Aspects 1. Basic Safety Aspects due to Physical properties and behaviour of Sulfuric acid. Basically, we know attention is paramount when adding water to a highly concentrated acid and this is the case with sulphuric acid which is highly risky. Sulfuric acid can have serious adverse effects like burns if it contacts the skin. This is due to the dehydrating properties of the acid on organic materials. Also, when the…

The gastrointestinal tract is significant to proper everyday functions. A large process in this region of the body is gastric acid secretion. This secretion occurs from a number of different mechanisms. However, this process is largely contrived through two means, parietal cells and drugs. Utilized each day in processes like digestion and metabolism, the role parietal cells and drugs play in regulating gastric acid secretion is fundamental to life. Gastric Acid Secretion by Parietal Cells…

The United states has one of the largest demand for energy in all forms. One common way to get the energy we need is through hydraulic fracking, but it has become more controversial as we know more about it. This paper will discuss what Hydraulic fracking is, what has been the recent controversy around it, and finally what effects the injection of wastewater has on the ground water and seismic geology of the region. Generally speaking, hydraulic fracking is the process of drilling a hole and…

In the past few centuries Earth’s climate has change dramatically with the increase of greenhouse gasses, and changes in global temperature. Global climate change has become a world wide spread issue. The international panel for climate change says global climate change is the result of the anthropogenic increases of carbon dioxide, and other greenhouse gases. “Soil biological processes have major long-term effects on composition of Earth’s atmosphere, which in turn influences all living things,…
