This is a chemistry lab report on an Acid-Base Titration experiment.
... Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration ...
History Of Titanium; Speeches
... titanium. Titanium is a hard, silvery-gray metallic element. Its atomic number is 22 and its symbol is Ti. It is the 9th most common element in the Earth's crust. It also is found in meteorites, the moon, and the sun. Titanium metal ...
The properties of glass explained by the bonding of Silicon and Oxygen.
... concentrated alkalis and acids. Alkalis work by attacking the silica directly and dissolving the glass, and acids work by attacking the alkalis in the glass. The corrosion of glass by acids is slowed down because a porous surface of silica is left with holes where the ...
Insulation
... textile trade because of its insulation. Woolen fabric is when the woolen system uses short or mixed long and short fiber where no combing is done. It has a rough appearance and is most suitable for blankets, overcoats, and tweeds. Denim which the experimenter is also testing is the ...
Moles Of Iron And Copper Formal Lab
... determine a couple things. What we were trying to determine was the amount of moles of copper and the amount of moles of iron in the chloride and in the nail. Procedure: 1. Put on your laboratory apron and safety goggles. Use a 100-mL beaker to make a solution ...
Photochemical Smog
... and its by-products form increasing concentrations of ozone. * At the same time, some of the nitrogen dioxide can react with the volatile organic compounds (VOCs) to produce toxic chemicals. * As the sun goes down, the production of ozone is halted. The ozone that remains in the ...
The Greenhouse Effect
... the earth was efficiently trapping a tiny portion of the sun's heat and keeping it near the surface to warm up the air just enough to prevent temperatures from plunging to frigid extremes every night- which, of course, is exactly what happens on the moon and ...
Alkalinity of aqueous systems
... solution by titration, by convention, the pH is usually about 4.5 for the alkalinity titration and 8.3 for acidity. When the solution titrated reached pH=8.3, the concentration of the volume of acid added equal to the sum of concentrations of the base solution, the carbon dioxide and the ...
Amino Acids
... can attack the body. Amino acids are a part of the enzyme and hormone system. Amino acids also help to build and form nucleoproteins such as RNA (Ribonucleic Acid) and DNA (Deoxyribonucleic Acid), which make up our composition. These acids transport oxygen through the body and aid in the generation ...
