Inorgnic Synthesis - Lab Report Example Test for SO42- required use of BaCl2 whereby the resulting component was a precipitate of BaSO42- whereas that of Al3+ yielded to a cloudy precipitate by adding KOH and disappearing in excess. During the experiment, the first step was to cut aluminum foil into small pieces, hence increase their surface area for effective and quick reaction. Afterwards, the prepared pieces of aluminum foils were put in a beaker having a capacity if 150 ml and its weight taken before they were put in a 250 ml whose weight together with its contents was 1104.7g. Then the rest of the experiment was transferred to the fume hood to void inhaling of obnoxious gases while reactions were in progress. 13 ml of 3M KOH were added in the 250 ml beaker coupled with stirring continuously to ensure all the aluminum pieces were completely dissolved. Observations made during this process encompassed bubbling reaction, black color and elevation of the contents’ temperature above the room’s ordinary. Upon completion of the entire reaction process, the contents were cooled to room temperature whereby the involved chemical equation was as follows, The cooled contents were then filtered using glass wool. This is by putting glass wool in a funnel and in 100 ml beaker whereby based on the resulting filtrate’s clearance one could do another filtration to ensure clearer resultant. There was rinsing of the glass wool (using 2 ml of hot water) before allowing resulting filtrate to cool and addition of 22 ml of 4M H2SO4. On adding of 23 ml of 4M H2SO4, the filtrate stated to change its appearance from black color to colorless before becoming dense near the bottom of the beaker. This was a precipitate while the reaction equation that took place encompassed, After the above reaction, the resultant was heat on a hot plate (5-10 minutes) to vaporize excess liquid to approximately 25 ml then testing

E-commerce and its Importance in Business Research Proposal - 1

E-commerce and its Importance in Business - Research Proposal Example At the end of the entire study and based on the conclusion, few recommendations will be also provided to further improve the process or how organizations, as well as consumers, can make effective use of it. Â  With the rapid development of networking technologies during the early 1990’s human being witnessed the commercialization of internet services (Kalakota and Whinston, 1996, p.147). From that era organizations across the globe started to incorporate the internet into their system of operations in order to gain competitive advantage and to create a core competency for themselves (Reynolds, 2004, p.5). At the same time that is in the early 1990s, the concept of e-commerce was also introduced (Kurth, 2011, p.6). Earlier E-commerce was considered to be a core competency for the organizations, however, at present, it has become a necessity to survive in the marketplace (Ardisana, 2000). Â  Electronic commerce or what is commonly known as e-commerce is an application which facilitates online selling and buying of goods and services (Zhou, 2004, p.56). It offers facilities such as online fund transfer, electronic data exchange (EDI), and online marketing among others. The major advantages of using e-commerce are the maximization of speed in the context of service delivery, reduction in the overall cost and also quicker response to the customers (Rajaraman, 2010, p.12). Electronic commerce also plays a crucial role in the online payment process. Online payment method refers to the process of directly transferring funds to the seller’s bank account (Radu, 2003, p.2). The biggest advantage of an online payment option is that it instantly completes the entire process of payment.
