A copper plate was dipped into a solution silver nitrate. After sometimes, a black layer was observed on the surface of copper plate. State the reason for it and write chemical equation of the reaction involved

Answer»

When the copper plate is dipped in silver NITRATE SOLUTION then a chemical reaction takes place,

  • Cu + AgNO₃ → Cu(NO₃)₂ + Ag

Hence, this is a displacement reaction where more reactive METAL (Copper) displaces LESS reactive metal (Silver) from it's compound (AgNO₃)

Therefore a new compound, Cu(NO₃)₂ is FORMED in this reaction which has a black colour deposit on plate.
