In order for a reaction to occur, a metal strip must have evidence of black or grey deposits on the surface of the metal once dipped into the solution. The copper is undergoing oxidation; therefore, the copper electrode is the anode. Chemical properties are based on the ability or inability of the substance to produce new substances. Station #6: Chemiluminescence. copper (II) sulphate. Follow the instructions at each station carefully. Use this demo to contrast the physical and chemical properties of matter. I am in 11th grade. Technical note: I set the slider on Silver Nitrate on purpose to jump in increments of 2 so that we do not end up with half an atom of copper left. In order to balance AgNO3 + Cu Cu(NO3)2 + Ag you'll need to be sure to count all of Ag, N, O, and Cu Cl atoms on each side of the chemical equation. This is seen clearly using a magnifying glass. 3- Every gray copper represent 1/2 oxidation process.
