1. Basic Copper Sulphate(WSDTY) assemble your safety gear. You will need eye protection, a lab coat or heavy long sleeve shirt to protect yourself from splashes, and acid-resistant (latex or nitrile) gloves. You should also keep a box of baking soda (sodium bicarbonate) on hand to neutralize any acid spills.

Sulfuric acid is highly corrosive. Be careful not to spill or splash it. If you get sulfuric acid on your skin, immediately flush your skin with soap and cool water for at least 15 minutes, and seek medical attention. If you splash sulfuric acid in your eyes, flush your eyes for at least 30 minutes with cool water and seek medical attention. WEAR GOGGLES to prevent this from happening!

2. Find a suitable workspace. This experiment will put off hydrogen (h2) gas, which is extremely combustible, and should only be done outdoors or under a laboratory vent hood, away from any open flames or ignition sources. You should also set up your experiment on an acid resistant surface, preferably one that is glass, or specific chemical resistant.

If you don't have a chemical-resistant surface to work on, you should at least put a sheet of thick cardboard under your work area. The sulfuric acid will dissolve the cardboard, but slowly enough that you can neutralize the spill with baking soda before it eats clear through.

3. Assemble your equipment. You will need a 6-volt battery, a glass jar or beaker, 2 lengths of copper wire, concentrated sulfuric acid solution (available at scientific supply stores), a glass measuring beaker or eyedropper, and water. If you do not have access to the concentrated sulfuric acid solution, you can use battery acid, which is 30-35% sulfuric acid and is available at hardware and auto parts stores.
