The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the

Analysis Jacob Pitcher and Derrick Gillespie Chemistry Lab 112 Section 02 4/02/2013 Abstract A sample of soil was tested for possible contaminants and other information using a variety of techniques including moisture analysis‚ pH measurement‚ acid-base titration‚ chloride-ion electrode analysis‚ and flame testing. The sample had a greater concentration of chloride ions‚ no measurable CaCo3 ‚ and lower than standard moisture content. It was contaminated with KCl and likely HCl ionic solids.

Chlor-alkali is an industrial process widely used to produce chlorine‚ caustic soda‚ and other chlorine and sodium derived/based products such as sodium hypochlorite‚ hydrochloric acid‚ chlorosulphonic acid‚ bleaching power‚ polyaluminium chloride‚ hydrogen gas‚ and chlorinated paraffin. The process uses brine (sodium chloride) solution during electrolysis to produce aforesaid products which are also known as Chlor-Alkali Industry /market products. The report estimates the market size of Chlor-Alkali

react with hydrochloric acid; and 1 cm3 of element X has a mass of 1.8 grams. Is element X a metal or non-metal? Give the reasons for your answer. Element X is most likely a typical non-metal. First of all‚ element X melts in boiling water; non-metals typically have low melting and boiling points. Furthermore‚ element X is unable to react with hydrochloric acid. This greatly indicates that element X is a non-metal as most non-metals fail to react with hydrochloric or dilute acids. In order

dissolved in 50ml of distilled water in 250ml of Erlenmeyer flask. 2. 60ml of 10% solution of ethylenediamine is added into the flask. 3. A vigorous stream of air is being drawn through the solution for about 1-2 hours 4. 35ml of concentrated hydrochloric acid is added 5. The solution is then being evaporated on a steam bath until a crust forms over the surface. 6. The solution is cooled and stand overnight before the bright green plates of the hydrochloride‚ trans-[Coen2Cl2]Cl.HCl is filtered

Discussion for Experiment 1 (Basic Laboratory Operations and Identification of a compound : Chemical Properties) In the first experiment‚ the precision of instrument was studied by measuring the mass of water for several times. The result shows that the mass measurement of the balance is precise since the masses of water in six trials are somewhat close. The reason that the masses of water in each trial are not identical may come from the high sensitivity of the balance that keep fluctuating due

The Ka and Molar Mass of a Monoprotic Weak Acid Chemistry Lab 152 Professor: James Giles November 7‚ 2012 Abstract: The purpose of this experiment was to determine the pKa‚ Ka‚ and molar mass of an unknown acid (#14). The pKa was found to be 3.88‚ the Ka was found to be 1.318 x 10 -4‚ and the molar mass was found to be 171.9 g/mol. Introduction Acids differ considerable as to their strength. The difference between weak and
