In the event of a nitric acid spill, cover the nitric acid with the sodium carbonate that is provided and evacuate the room if necessary. At the beginning of the experiment, the pure elemental form of copper (Cu) is oxidised by the silver nitrate solution. This is the Base Model in Chemistry of Silver Nitrate and Copper. Select all those that are chemical reactions or chemical changes and not just physical changes (mixing). When copper atom reacts with a silver ion, it turns gray as an indication of a change in oxidation state from 0 to +1. Nov 30th, 2021 Published. Overall, putting these different strips of metal into different solutions will help determine the reactivity of copper, lead, zinc, magnesium, silver and hydrogen., Copper is find in ores, an ore is a type of rock that contains minerals with important elements including metals, there is a lot of different copper ores such as Chalcopyrite, Covellite, Malachite, Azurite:, Ans: We can experimentally let the light to pass through a prism which will allow us to see whether copper solution is blue, green or both colors as the prism will be able to separate the two colors as they bend differently according to their wavelengths .If its one color we will see it after passing through the prism and if its both colors will know the which one of them has, Chemical changes are often accompanied by physical changes.
