Vanadium redox batteries, upgraded electrolyte and R2 catalyst. The VRB energy is stored chemically in different ionic forms of vanadium in a dilute sulfuric acid electrolyte. This creates a current that is collected by electrodes and made available to an external circuit. The reaction is reversible allowing the battery to be charged, discharged and recharged. This technology is one of the only socially responsible energy storage options in existence. As a "green" technology, the VRB is characterized

linked to asthma attacks. Acid rain also is a problem created by air pollution. “Acid rain (or acid deposition, as it's called in technical circles) is produced by the burning of fossil fuels. It is formed when emissions of sulfur dioxide and nitrogen oxides react in the atmosphere with water, oxygen and oxidants to form various acidic compounds. These compounds then fall to the ground in either wet or dry form.” (http://www.cleanairtrust.org/acidrain.html). This acid rain can get into our waterways

Current Event Assisgnment Tyler Roach 1. Baking Soda is the common name for Sodium Bicarbonate. 2. Chemical manufacturers and importers need to test the dangers of the chemicals and prepare the labels and MSDS sheets for them before they give them to the public. Also, all workers who are working with dangerous chemicals must have labels and MSDS sheets for their coworkers who are exposed to this chemical, and teach their coworkers a safe way to handle the chemicals properly. 3. They are

Can a Cabbage Distinguish an Acid from a Base? For this activity, Chemistry students have prepared cabbage juice and have set up workstations in the classroom for you to explore acids and bases. You will use your observations to classify some common household items as acids, neutral substances, or bases. Whenever we work with chemicals, it is necessary work carefully and to wear aprons and goggles. How does it work? Red cabbage contains a pigment molecule known as an anthocyanin. This

Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases. Bases feel slippery, change litmus blue, and become less basic when mixed with acids. While Boyle and others tried to explain why acids and bases behave the way they do, the first reasonable definition of acids and bases would not be proposed until 200 years later. In the late 1800s, the Swedish scientist Svante Arrhenius proposed that water can dissolve many compounds by

bleached oil. 7. Steam generator: generate steam distillation. Cooking oil refining machine working only need 5 steps: 1. Crude Oil Degumming: In this step gums in crude oil are removed by hydration with the help of phosphoric acid. 2. Neutralization: In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap. 3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become

and effective ways to genetically-engineer natural flora of pest insects in order to create a recently discovered insecticidal protein. The indole test was used in this lab. This test determines whether the microbe produces indole from the amino acid tryptophan. The media used are the Sulfide-Indole-Motility (SIM) medium and Tryptone broth medium. This is very essential in the field of microbiology because it has a content that limits bacterial swimming. Procedure: What I did first was to
