1. An oxidising agent is a substance that accepts electrons from another substance, causing the other substance to be oxidized, while the oxidising agent itself is reduced. 2. Step 1: Identify the reaction. When copper metal is added to silver nitrate solution, a displacement reaction occurs: Cu(s) + 2AgNO_3(aq) Cu(NO_3)_2(aq) + 2Ag(s) Step 2: Explain the colour change. The solution turns blue because copper metal (Cu) is oxidized to copper(II) ions (Cu^2+), which form the blue copper(II) nitrate solution (Cu(NO_3)_2(aq)). Step 3: Relate to oxidising strength. Silver ions (Ag^+) are stronger oxidising agents than copper ions (Cu^2+). This means Ag^+ ions have a greater tendency to gain electrons (be reduced) than Cu^2+ ions. Consequently, Ag^+ ions readily accept electrons from copper metal, causing copper to oxidize and the solution to turn blue. Send me the next one 📸
