A Sequence of Chemical Reactions: Transforming Copper Briefly describe. a) Why must you carry out the oxidation of Cu with HNO3 in a fume hood? Concentrated nitric acid is a toxic oxidant. Avoiding skin contact or inhalation is highly important. The reaction between Cu and HNO3 produces NO2‚ a toxic brown gas; therefore working under the fume is necessary in order to prevent inhaling the toxic gas. b) Why you should be particularly careful when you work with 3 M H2SO4 solution?

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron
