Silver is more reactive than copper and platinum. Silver tarnishes easily when exposed to air, while copper only reacts slowly with air over time. Platinum is the least reactive of the three metals and remains largely unaffected by air and water.
To displace silver from a copper sulfate solution, you can add metallic copper to the solution. The more reactive copper will displace the less reactive silver, leading to the formation of copper sulfate and elemental silver. This is based on the principle of displacement reactions in which a more reactive metal displaces a less reactive metal from its compound.
Copper is more active than silver. Copper reacts more readily with other substances compared to silver, which is less chemically reactive.
No, copper will not displace silver from silver nitrate and silver will not displace copper from copper nitrate. This is because the reactivity series dictates that silver is below copper, so copper can displace silver but not vice versa.
Gold reacts the least out of copper, gold, iron, and silver. Gold is a noble metal, which means it is less reactive and does not easily corrode or tarnish when exposed to air or moisture. Copper, iron, and silver are more reactive than gold and can form oxides or other compounds more readily.
When silver nitrate is added to copper, a redox reaction occurs where the Cu from copper displaces the Ag from silver nitrate. This results in the formation of copper nitrate and silver metal as a solid precipitate.
