- When all the crystals are dissolved, stop heating, remove from the beaker from the hotplate, and place it on a thermal pad or wire gauze. While stirring, carefully add the iron filings to the hot copper sulfate solution.When all the iron has been added, let the solution react for ten more minutes.ince the number of moles of iron that reacts will be equal to the number of moles of copper produced, the number of copper atoms produced should be the same as the number or iron atoms we start with. You will first make a copper sulfate solution by dissolving copper sulfate crystals in hot water.

- Instructions. Unscrew the nut that goes over the compression fitting. You can get it free with a wrench or lock-jaw pliers. If the nut is difficult to remove, spray it with lubricant.Be careful not to twist or kink the copper tubing while removing the nut.f you nick the copper tubing even a little, a new compression fitting will not seal. Put a screwdriver into the slot you cut in the ferrule and twist it. Your goal is to pry the ferrule off, breaking the thin piece of brass holding the fitting together without denting or bending the copper tubing.

- As solvents quickly evaporate you should immediately assemble the fitting and the pipe. Push and twist (1/4 turn) the fitting onto the pipe until it bottoms out and hold the parts together for 30 seconds to avoid push-out. The softening effect of solvent can permanently distort or weaken your pipe, so at this time remove all excess cement using disposable material.

- 1 Suspend your rusty part from the pipe or stick with wire, submerged, making sure it does not touch the steel basket lining the bucket. Do not use copper like I did. Use steel wire, the same as for the cage. Make sure the two poles ( positive and negative ) never touch.  Make sure your work area is well vented! Unplug your 12-volt battery charger. Set it to about 2 amps. Hook the positive (red) lead to the bucket basket and the negative (black) lead to the rusty part lead. Plug the charger in and look at the meter; it should be drawing about 2 amps.
