- Initially, there will be no reaction.

- After a few minutes, a white precipitate of Lead(II) nitrate will form.

- The precipitate will settle at the bottom of the container.

- The supernatant liquid will be colorless and clear.

Chemical reactions taking place:

- The Zinc ions from Zinc nitrate react with the Lead ions from Lead solution, forming Lead(II) nitrate precipitate.

- The nitrate ions from Zinc nitrate remain in the solution as spectator ions.

$$Zn(NO_3)_2 (aq) + Pb(NO_3)_2(aq) ⟶ Pb(NO_3)_2(s) + Zn(NO_3)_2(aq)$$

The Lead(II) nitrate precipitate is insoluble in water and will settle at the bottom of the container. The Zinc nitrate solution is still colorless and clear, indicating that there are no dissolved Lead ions remaining in the solution.
