Metal M forms M²⁺ ions. A strip of metal M is placed in an aqueous solution containing N²⁺ ions and nitrate ions. The formula of the dissolved salt is N(NO₃)₂. After a short time, a solid deposit has formed on the strip and the concentration of N²⁺ ions in the solution has decreased.
Write the ionic equation for the reaction. Include state symbols.
Explain why nitrate ions are not included in the ionic equation.
