Question #739af

Answer 1

All nitrates are soluble; `PbX_2` is insoluble.

Explanation:

`Pb(NO_3)_2(aq) + 2KI(aq) rarr PbI_2(s)darr + 2KI(aq)`

Of course I could make this a net ionic equation. However, this question illustrates aqueous solubility rules. All nitrates are soluble; this allows us to get `Pb^(2+)` or `Ag^(+)` into aqueous solution. Most halides are soluble. The exceptions are silver halides, mercurous halides, and LEAD HALIDES. `PbI_2` wil precipitate from solution as a yellow solid. You should have done experiments to illustrate the reaction.
