Research Question:
What is the effect of opposite types of chemical compounds on the composition of atomic number 29?
Hypothesis:
If copper is exposed to different chemical compounds such as pollutant water (mixture of sulfuric mordant, hydrochloric acid and nitric acid), acid, and base, it leave behind show visible results within 30 days.
Qualitative Data:
Get five clean containers and a cover, Measure the numerate of chemical compounds we are going regulate into a container with graduated cylinder. Pour it in, and after 30 days, witness our data. We allow for be able to determine which compound repair copper the most by using spectrophotometer method. And for polluted water, we willinging wreak sulfuric acid, hydrochloric acid and nitric acid electropositive carbon dioxide by gently blowing water with a wheat before putting in any harmful chemicals. We will use clean/purified water as our constant.
Scientifically crucial:
We will be able to determine how much pelting mixed with different chemicals could affect on statues, buildings and other lifelike resources.
Sample Data Table:

How will we measure the differences and affects?




We will gather our chemical compounds (Polluted water, base, acid, and clean/purified water) that will be employ for our experiment, and pour one type of chemical compound into the container that has copper and blocker set up. After 30 days, we will wit the container gently to make sure we get all the misrepresented coppers that is above blocker. We will open up the cap, remove copper, and and so remove blocker with a forceps. Then, we will use spectrophotometer, add few drops of concentrated ammonia water (ammonium hydroxide) and copper will react with solution of ammonia, producing the blue color. We will determine the amount of copper in an unknown solution by purpose the relationship between concentration of copper ion and the amount of animated absorbed by the samples. First, set absorbance at 420nm then, record the class period at 20nm increments ~ 720nm increments. Using the...If you want to get a profuse essay, order it on our website: Orderessay
