reaction will go. I also predict that a strong acidic or basic solution will slow down or prevent the reaction. Materials and Methods On February 12th 2013‚ at 2pm we began our experiments. We first had to create and extract the catechol oxidase from potatoes‚ which we did by blending whole potatoes and DI water in a blender for approximately 30 seconds. Once the puree was made‚ we immediately put it on ice‚ in an attempt to slow down the conversion to benzoquinone. To test the

Purpose Use a standardized potassium permanganate solution to analyze an unknown iron solution by using redox titration. Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly

did not choose the career path as a pharmacy technician it tend to choose me. It seemed to be the right career for me because I’m more of a behind the scene type of person rather than in the spotlight. I really like to do office type of work and to work with different types of medication.

I feel this is the

EXTRACTION OF METALS SUMMARY Most metals exist in compounds in rocks in the Earth’s crust. Many of these ores contain oxides or sulphides of the metals. The compounds need to be reduced to produce the metals as elements. Metals are very useful to us because of their special properties. Reduction means removal of oxygen or gain of electrons. Carbon is a good chemical reducing agent because it readily combines with oxygen‚ but it is only useful for the metals below it in the Reactivity

Chinese Tea: Chinese Tea has a very long and complex history that dates back a few millennia. According to Chinese legends‚ a Chinese inventor and emperor was the first person to discover tea in 2737BC.
