Filter paper Saturated KNO; solution 259 Figure 1. Experimental apparatus. Experimental Procedure Part 1. Copper and Zinc Metal 1) Select a piece of copper and a piece of zinc metal wire from the containers in the hood. 2) Clean the surface of the metal wires with the steel wool. Wipe clean with a dry paper towel. 3) Obtain a plastic well plate. Fill one well with 10 drops of the Copper ion solution from the dropper bottle. Label this well with a Sharpie marker so that you remember which solution you filled it with, 4) Repeat step 3 with Zinc ion solution. Select a well right next to the well in step 3 so that the two wells with Copper and Zinc ion solution are right next to each other. 5) Obtain a small dry strip of filter paper. You may have to cut a large piece of filter paper down to the appropriate size. It should be exactly this big C It's OK to tear the filter paper with your hands. Using the drop bottle, saturate the filter paper strip with KNO; solution. Gently place one end…
