Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

Robert Lawrence and Edmund Stephens‚ two graduate students of geology from Columbia University‚ organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1‚000 grams of seawater contains approximately 35 grams of various salts‚ the two men pictured limitless wealth for themselves by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so‚ the men decided to begin producing it. They picked New Iberia‚ Louisiana as the ideal

effects of rock salt‚ which is used for melting snow in the winter time‚ works in a variety of ways. The main reason is to aid in melting of the snow making it easier for individuals to drive their vehicles and also the sidewalk for pedestrians. Overall‚ the rock salt used for melting snow‚ works but it have some pros and cons about it‚ but using it wisely should be the key to its success. Might grass growth be inhibited by salt?

opinions on the issue of the “Tar sands” or “Oil sands” (I shall use both unambiguously) development. Environmentalists (like myself) and concerned citizens in Canada‚ as well as the international community‚ decry that the largest industrial energy project on the face of the planet is destroying future generation’s right to clean soil‚ water‚ air‚ biodiversity and most importantly a stable climate. As well as strong local economy‚ the current economic setup of the tar sands’ development is to focus on

and I have been asked by the head office to write a report about the South Port Sand Dune system. Part 1: Kennedia Prostrata: Kennedia Prostrata is commonly known as the ‘Running Postman’. The Running Postman can spread up to 1.5 metres‚ followed but cylindrical pods that are 3cm-5cm in length. The Kennedia Prostrata has a light green leaf that contain 3 rounded leaflets. The species are naturally adapted to sand or light soil. That means that it is easy to maintain and can planted where it needs

The shortage of natural sand makes the artificial sand necessary. For the production of artificial sand‚ Hongxing Machinery exports remind you that choosing a right sand production process for artificial sand is just like water for fish‚ which is of high efficiency. Currently‚ aggregate crushing plant requirements in ghanathere are two ways of sand making: wet type sand making technology and dry type sand making technology. So‚ which one can be selected according to individual circumstance? At first

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical
