| 1. The independent variable of this experiment is the type of electrode used. The dependent variable is the voltage. The constants of this experiment are the following: the amount of electrolyte used, the length of wires and the size of copper sheets used. 2. Take necessary safety steps by putting on goggles and gloves. 3. Rub the copper, zinc and lead sheets against the sandpaper to remove any deposits. 4. Pour 100ml of zinc nitrate solution into a beaker. Put the zinc sheet into the solution. 5. Pour about 50ml of copper nitrate solution into the porous cup and ..... | ||
