Silver and Copper Lab

  Lab

- Soooooo I was gone for majority of this lab, but hey! I'm going to try my best thanks to some help my friend Serena!

Materials:

-Silver Nitrate

-Copper

-Distilled Water

-Test Tube

-Filter Paper

-Funnel

-Beaker

Procedure for Day #1:

Step 1-Obtain 30cm of bare copper wire. Clean the wire, then coil it around a pencil to form a loose spring. Make sure that the other end of the wire reaches the top of your test tube and is uncoiled.

Step 2-Weight the coil with a balance, then place the copper wire in the test tube to check that is is the correct length. Remove the coil and set it aside for later.


Step 3-Weight the weighing dish of silver nitrate and record it's number.


Step 4-Transfer the contents of silver nitrate to your test tube.


Step 5-Pour distilled water into your test tube until the water is about 2 cm from the top.


Step 6-Cover the top of the test tube with parafilm.


Step 7-Place your thumb on top of the test tube and invert it until all the silver nitrate is disolved.


Step 8-Weigh the empty weighing dish so that you can determine the mas of silver nitrate that was added to the test tube.


Step 9-Add the copper coil to the test tube.


Step 10-Set the tube aside until the next day or class period.


Step 11-Make sure you record all data!

Procedure for Day 2!! (I was here for this part!)

Step 1- Weigh a piece of fiter paper for use in separating the silver.



Step 2- Shake the test tube and copper wire to dislodge the silver.

Step 3- Set up a funnel with your filter paper in it.


Step 4- With a waste beaker beneath the funnel, lift the copper wire out of the test tube and hold it over the filter system.


Step 5- Using a water bottle, let distilled water run down the wire so that any silver will wash into the filter.


Step 6- Lay the copper wire on a labeled piece of paper to allow it to dry.


Step 7- Pour off the solution in the test tube through the filter paper into the filter, trying to keep the silver precipitate in the test tube.


Step 8- Rinse with distilled water and decant several times into the filter to wash the silver.


Step 9- Finally wash the silver from the test tube onto the filter paper.


Step 10- Allow to dry overnight.

Procedure for Day 3!!

Step 1- Weigh the copper coil and record it's mass.



Step 2- Weigh the silver and filter paper - record the mass.
