The aqueous ions are Na+ and I- .
Aqueous lead nitrate plus aqueous sodium iodide produce solid lead iodide and aqueous sodium nitrate.
Pb(NO3)2(aq) + 2NaI(aq) → PbI2(s) + 2NaNO3(aq) Aqueous lead II nitrate reacts with aqueous sodium iodide to form solid lead II iodide precipitate and aqueous sodium nitrate.
Pb(NO3)2(aq)+2NaI(aq)=2NaNO3(aq)+PbI2(s)

Aqueous lead nitrate plus aqueous sodium iodide produce solid lead iodide and aqueous sodium nitrate.
Lead(II) nitrate and sodium iodide undergo a double displacement reaction to form sodium nitrate and lead(II) iodide, which is a slightly soluble yellow solid. The balanced chemical equation for this reaction is: Pb(NO3)2(aq) + 2NaI(aq) -> 2NaNO3(aq) + PbI2(s)
When aqueous solutions of silver nitrate and sodium iodide [note correct spelling] are mixed, silver iodide solid precipitates from the mixture.
Pb(NO3)2(aq) + 2NaI(aq) → PbI2(s) + 2NaNO3(aq) Aqueous lead II nitrate reacts with aqueous sodium iodide to form solid lead II iodide precipitate and aqueous sodium nitrate.

Sodium sulfate can exist in both forms: as a solid (crystalline powder) and in aqueous solution when dissolved in water.
You can separate a mixture of iodine solid and sodium iodide by using the difference in solubility of the two compounds. Since sodium iodide is soluble in water while iodine is not, you can dissolve the mixture in water to dissolve the sodium iodide, leaving the solid iodine behind. The two can then be separated by filtration.

Yes, it is correct.
To obtain solid lead iodide from 20cm3 of aqueous lead nitrate, you would need a source of iodide ions (e.g., potassium iodide), a filtration apparatus to separate the solid lead iodide from the solution, a beaker or container to collect the solid, and a drying oven or desiccator to dry the collected solid. Optional equipment includes a stirring rod and a hot plate to facilitate the reaction.
The filtrate of lead nitrate and sodium iodide would contain soluble sodium nitrate and insoluble lead iodide. Lead iodide is a yellow solid that precipitates out of the solution, while sodium nitrate remains in the filtrate as it is soluble in water.
