Silver Nitrate/ Copper Lab

 The first day of this lab we weighed out exactly one gram of silver nitrate and got a piece of copper and measured that out to be 3.444 grams. We put the silver nitrate in a test tube with water and coiled up the coper to make it fit in the test tube. Then we shook it up a little to mix the copper nitrate up. We then put a  parafilm cover over the top of it and let it sit over the weekend. The result was that the water turned blue from the copper and the silver nitrate built up around the coiled copper. The second day we took the copper out and poured it into a little filter with a beaker on the bottom and washed the nitrate off the copper.n The 3rd day, we weighed the copper and recorded its mass, then weighed the filter paper and recorded it's mass.   Mass of everything.
Silver Nitrate: 1.369 grams.
Copper Coil before: 3.68 grams
Copper Coil after: 3.26 grams
Copper Reaction: .423 grams
Filter Paper: 1.389 grams
Filter paper and silver together: 1.892 grams
Silver production in moles: .0032 moles
Copper Consumption: .0036 moles.
