In the first reaction, after adding the KOH solution to the beaker with the clean aluminum strips, the solution turned to a dark purple color, almost appearing black at times. The aluminum clearly began to dissolve, when it was visible in the solution, and bubbles began to form on the surface of the solution. As the solution was allowed to cool following the reaction, the bubbles and the vapor given off by the mixture (causing the necessity for venting during this experiment) became far less apparent. Following the reaction and the proper carrying out of the filtration steps multiple times, the solids were removed from the reaction mixture and a colorless filtration mixture was left in the reaction beaker.
Adding 20mL of 6 M. sulfuric acid to the colorless filtration liquid caused the mixture to become cloudy and white, and solid precipitates began to form. These chunks were broken down and dissolved by the heat of the hotplate and the ongoing reaction taking place in the beaker, and by the end of the reaction the solution was clear and colorless. An ice bath was then prepared, and without the...
The filter apparatus was again set-up and utilized to remove the crystals from the mixture, with the beaker being rinsed twice with 10mL of the 50% ethanol solution. The alum crystals were dried in this fashion as well, to allow for more accurate weighing of the crystals for analysis. The now cleaned-and-dried beaker was again weighed (104.3153g) and the alum crystals were then added to the beaker and the weight again obtained (109.1553g), with the difference (4.84g) being the weight of the alum crystals formed in the sequential reactions. Using the starting weight of the aluminum strips and the final weight of the alum crystals it is possible to determine the quantities of the reaction elements.
Conclusion
Reclycing aluminum is not as energy intensive as mining aluminum and can be achieved with fairly simple chemical reactions. This experiment demonstrated the ease of certain aluminum-based reactions with fairly standard lab equipment and chemicals. Alum crystals were created from aluminum cans.
In the absence of proper waste management laws and regulations, as well as poor enforcement of existing waste disposal laws, an increase in the number of manufacturing entities would inevitably increase instances of water pollution. According to Goel (2006), the mere fact that smaller cities report less instances of water pollution than larger cities is a clear indicator of the relationship that exists between population density and water pollution
The fact is that numerous rooted macrophyte structures are not full of naturally strong and healthy particles and sediments and nutrients. It is because of the restriction or absence of these particles, sediments and nutrients that the study of these systems has not been as extensive and thorough as the concentration on the terrestrial structures when understanding the fate, sources and sinks of Co2 levels in the ecosystems and the
The feedstocks that are considered include going back on coal Gasification, and coal liquefaction, stranded natural gas and oil which was heavy and available from the 'oil shale' or 'tar sands', and biomass. Because of its eco friendly nature and sustainability biomass is to be considered as the better alternative. There are some technical barriers that have to be overcome in using biomass as alternate feedstock. Governments are now
The former might be, 'What specific...' [while] Less structure might be exemplified by: "Please respond to the following in your own words: I....'" (Dereshiwsky, 1999) in addition: adding some open-ended items such as these to a more traditionally scaled quantifiable survey, such as one with Likert-scaled attitudinal items, and/or "check/off" questions on demographic background variables, is a good way to make the survey "multimethod" in nature. This is because you'd
Management Strategy to Utilize Meta-Analysis Technique for Nuclear Energy and Waste Disposal and Create Social Sustainability This research proposal explores the link between public perceptions of nuclear power, how those perceptions are formed, and what influence those opinions have on energy policy. These issues are important in light of two realities. First, nuclear energy is declining in its share of global energy. Second, nuclear energy offers what might well be
