The equation ZnNO3 + Ca(OH)2 -> Ca(NO3)2 + Zn(OH)2

  1. The chemical equation above describes the ion exchange reaction between zinc nitrate (Zn(NO3)2) and calcium hydroxide (Ca(OH)2) to form calcium nitrate (Ca(NO3)2) and zinc hydroxide (Zn(OH)2).

  2. Reaction conditions: This reaction occurs at room temperature and standard pressure.

  3. Reaction process: In this reaction, the nitrate ion (NO3-) of zinc nitrate is exchanged with the hydroxide ion (OH-) of calcium hydroxide, forming calcium nitrate and zinc hydroxide.

  4. Occurring phenomena: During the reaction process, we can observe changes in the color and shape of the reactants. Normally, zinc hydroxide (Zn(OH)2) will precipitate out as a white solid.

Note: The above equation is not balanced. The balanced equation will be:

Zn(NO3)2 + Ca(OH)2 -> Ca(NO3)2 + Zn(OH)2
