                                                       When I Cu around

Purpose: To learn what effects different reactions have on copper. In the experiment, copper will go through a series of  different test designed for students to see what exactly is happening in different situations and how copper reacts to other elements. Most importantly, the experiment will show that Matter cannot be destroyed.

Background:
Many people have tried (and failed) to create gold. Is it actually possible to turn matter from one substance to another? The answer is no, unfortunately (but also fortunately, in many ways) we can not turn another substance into gold, or anything else for that matter (no pun intended). This experiment will prove that.

Materials:
250 ml beaker
100 ml beaker
2 graduated pipettes
50 ml graduated cylinder
funnel
filter paper
scoopula
copper powder (.1 g)
8 M nitric acid  H2S04, (2 ml)
1 M sulfuric acid, H2SO4 (15 ml)
8 M sodium hdroxide, HaOH (2 ml)
Stirring Rod
Hot plate
beaker tongs
balance
zinc filings, (.1 g)
25 ml of water




Procedure:
Measure the copper (.1 g) and place the measured copper into the fume hood. Measure 2 ml of the 8 M Nitric acid  H2S0  and mix it into the copper. Observe the reaction.
After the brown gas is no longer being produced take the beaker out from underneath the fume hood. add 25 ml of water to the beaker. and then add 2 ml of the concentrated sodium hydroxide HaOH and slowly pour the liquid into the 250 ml beaker. Observe.
Put the beaker onto a hot plate (on medium heat) and stir the liquid with a stir rod until the concoction is a dark green colour and little specks of a solid begin to appear. Use the tongs to remove the hot beaker from the hot plate and onto the lab bench.
Set up the funnel contraption as shown:







use a scoopula to scrape whatever remains in the filter and place the (looks like a dark brown powder) substance into the 100 ml beaker stir in 15 mL of 1 M sulfuric acid, H2SO4. Observe the changes.
(this is what it looks like)


Measure .1 g Zinc filings and add to the 100 ml beaker. Observe the changes.

Proper dispose of the liquid into the correct waste disposal. Ask you teacher . Clean up your area and glassware .


Safety:
Wear closed-toe shoes, an apron and goggles. Be sure to use the fume hood and properly dispose of chemicals.
