Extract of sample "Water quality method for chemistry"

Download file to see previous pages The materials used in the experiment included the surface water test kit. The kit was from Hach Company. While conducting the experiment, safety procedures were fundamental; since the water was hazardous, protective clothing such as globes was important (W.H.O 114).  The test kit contains all materials required to perform the experiment, for example, reagents for testing chlorine content in water (Sturman & Kuruvilla 77).
  There are other materials such as test tubes to put the surface water before adding reagents to test for various parameters.  With the help of a Grab sampler, collection of water samples was easy.  After collecting the water sample, appearance evaluation was present to determine the color, turbidity and presence of organic materials.  From the sample, odor was determinable via wafting.  The amount of dissolved oxygen in water was determinable via adherence to procedures from the test kit (W.H.O 116).  A PH meter from the test kit indicated the level of PH in the water sample.  The recording of water temperature was possible by following the test kit directions.  The nitrate test entailed additions of zinc sulfanilamide to the water sample and the results recorded.  The Hach kit aided determination of ammonia plus chlorine by following instructions from the Kit.  All the results from the tests were in records by all members of the group (Sturman & Kuruvilla 78).
Observation of the water sample indicated clarity with small amounts of suspended solids. The water was clear, meaning that there was no color. ...Download file to see next pages Read More

...Question 2-What is the effect of an insoluble impurity, such as sodium sulfate, on the observed melting point of a compound? Insoluble impurities, although very. undesirable, will not affect the melting point. Question 3-Three test tubes, labeled A, B, and C, contain substances with approximately the same melting points. How could you prove the test tubes contain three different chemical compounds? Even if two different compounds have the same melting point, if they are mixed together the melting point of the mixture will be lowered because the compounds are no longer pure. You would take a sample from two of the compounds, X and Y, mix them. If the result of a lowered melting point is present, then the two are different... 2-What is the...

... In this lab, we aim to build a working model of a self heating cup using the heat released during an exothermic reaction. We shall also compare two chemical reactions to find which reactant causes water in the cup to reach higher temperature in a shorter duration. Hypothesis In the experiments, we assume that there is no heat loss during the reaction – the heat released during the reaction is equal to the heat absorbed by water in the cup. The apparatus is open to the atmosphere and so pressure is constant throughout the reaction (Myers). Variables Independent variables: amount of calcium chloride in g, amount of copper sulfate + zinc in g, time of reaction is 10 minutes. Dependent variables: initial temperature of water in °C, final...

For example, steel containing a higher percentage of Mn is suitable for production of complex tools and durable machine parts. Contrarily, steel containing a substantial percentage of chromium is used to produce metallic parts that resist corrosion. In this case, quantitative determination of transition elements in steel is significant in industrial chemistry.
Primarily, steel is made up of iron but it contain trace amounts of transition metals like manganese, chromium and copper among others. In practice, the actual amount of each element in a steel alloy can be determined quantitatively. This lab exercise covered on quantitative determination of manganese Mn in an unknown sample of steel. Determination of Mn in steel took ad...

Total Quality Management

The premise of Total Quality Management was laid out by Deming as fourteen principles, which emphasize the importance of quality and a focus upon the customer in internal operations. (Anonymous, 2006). Deming’s approach requires that continuous improvements take place with the training of employees so that it results in the reduction of costs and thus helps an organization compete more effectively in the marketplace. This approach also calls for increased levels of innovation, diffusion, and adoption in management (Ehigie and McAndrew, 2005). It is the innovation that helps an organization to gain a competitive edge over its rivals in the marketplace by developing new ideas but the process of diffusion helps to ensure that t...

The Problem of Surface Water Acidification

The marked effort by authorities and environmental agencies to contain this phenomenon on its detrimental effect on clean water and agricultural products, the main concern is that these pollutants are also impacting negatively on the bird populations and other aquatic forms (Haliwell et al, 456).
There has nonetheless been a significant decline in acidic levels on the surface waters since their peak levels in the late 1970s on a number of areas within the United Kingdom, especially in sulphuric acidity. This has been credited to local and international policy regulations and legislations e.g. the Convention of Long-Range Trans-boundary Air Pollution and the European Union. They include the Gothenburg Protocol of 1999, th...

The Quality of Democracy in Britain

The network method comprises a chain of networks that influences stiff policy communities to open issue networks. Pressure groups achieve a result by influencing the public policy process through exchanges and interchanges made by members of a number of networks. The participants of these networks include members of interest groups, professionals, pressure groups and voluntary organizations. Networks have gained much significance due to the string of communication that takes place between non-governmental and governmental players and private and public sectors in recent years (Peele, G 2004 p.336).

How Do Customers Assess Service Quality of Retailing Websites

Given the emergent nature of online commerce, it is a tough task for retailers to develop a website that meets all expectations from consumers. This view is supported by a survey conducted by the UK’s largest e-consultancy Cap Gemini. The survey identified several key disadvantages for online shoppers. Some of these include “’ Availability’, ‘Can’t be in to receive delivery’, ‘Premium charged for delivery’, ‘Can’t see or feel the merchandise’, etc.” (Quader & Quader, 2008) These are not trivial complaints by any means and despite the e-retailing industry setting foot into its third decade in existence, there are no satisfactory solutions found for th...
