The equation Cu(NO3)2 + Zn -> Zn(NO3)2 + Cu

  1. Detailed information about the chemical equation:

The above chemical equation describes a substitution reaction between copper (II) nitrate ion (Cu(NO3)2) and zinc (Zn), forming zinc (II) nitrate ion (Zn(NO3)2) and copper (Cu). This reaction is a type of redox reaction, in which zinc is oxidized (increasing its oxidation number from 0 to +2) and copper (II) ion is reduced (decreasing its oxidation number from +2 to 0).

  1. Reaction conditions:

This reaction easily takes place under normal conditions, without the need for special conditions. It only requires ensuring the contact between zinc and copper (II) nitrate solution.

  1. Reaction process:

When zinc is added to the copper (II) nitrate solution, zinc is oxidized to zinc (II) nitrate ion and copper is reduced back to metallic copper. This process occurs easily because zinc has a higher chemical activity than copper.

  1. Occurring phenomena:

When the reaction takes place, you will see the color of the solution change from sky blue (the color of copper (II) ions) gradually to colorless (the color of zinc (II) ions) and the appearance of brownish-red copper particles settling at the bottom.
