Nickel metal is added to a solution of copper (ii) nitrate. express your answer as a chemical equation. identify all of the phases in your answer. enter no reaction if no reaction occurs.

Nickel is the 28th chemical in the periodic table and the chemical symbol of copper (II) nitrate is Cu (NO₃) ₂. The chemical reaction that occurs between these compounds is a single-replacement reaction.

From the activity series of metals, nickel is able to replace copper in the compound and this is expressed in the balanced equation,

Ni (s) + Cu (NO₃) ₂ (aq) - - > Cu (s) + Ni (NO₃) ₂ (aq)

The phases are also written in the equation.
