will carry out in an experiment. This experiments should help us answer the research question which is aforementioned. There are many factors which could influence the conductivity of ionic substances. For instance the position and depth of the electrode used to transfer the electricity to the solution could have an effect on wether ionic solutions can conduct well or not. While it is proven that Ionic solutions dissolve in water and can conduct electricity the dissolve poorly in any other solution

9-volt battery into the snaps on the battery cap (Figure 1). 5. Let the demonstration run for 5–10 minutes and note the changing colors over time and the production of gases (bubbling) at each electrode. A deep purple color forms immediately at the negative electrode‚ while at the positive electrode a red- orange color appears more slowly. Over time‚ a wider range of universal indicator colors—purple‚ blue‚ green‚ yellow‚ and red—may develop

promise as electrode material for Li-ion batteries‚ owing to large surface area‚ shorter Li-conduction distance and high electrical conductivity. However‚ practical application of such Li-ion batteries demands higher volumetric capacity‚ which is otherwise low for most nanomaterials‚ used as electrodes. In order to address this urgent issue‚ we have developed a novel 3-dimensional (3D) anode‚ based on multiwall carbon nanotubes (MWCNTs)‚ for Li-ion batteries. The unique 3D design of the electrode allowed

Most people wake up to an alarm or radio. These common household items contain batteries‚ which make them very chemically dependent. These batteries contain positive and negative electrodes. The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese dioxide. The negative electrode is made of zinc. Chemistry plays an important role in the discovery and understanding of materials contained in these and many other common household items. Things like household cleaners

Unlimited Power Supply Before I came up wit the U.P.S. (Unlimited Power Supply)‚ I was struggling with an idea for this science fair. However I thought of a magnetic car. Then after school I heard my parents saying that our electricity bill was getting too high‚ so I tried to think of a solution. Then I read an article about how a Prius battery could power a house‚ and then I thought about how I could power a house using a rechargeable battery like is found in the Prius. Then I came across the Bedini

The topic I am researching for my I-Search is welding. The reason I want to be a welder is because it is something I really enjoy doing and many of my family members are welders. Welding has many ups to the job but it also has its downs to it also.The ups to the job are it pays well in the beginning and the more experience you have the more you make and you also get to admire the work you did. The downs to the job are you tear down your body very quickly and also have the chance to have a pipeline
