Question

What, if any, precipitate forms if aqueous solutions of lead(ii) nitrate (pb(no3)2) and sodium acetate are mixed?

Answer 1

Lead(II) nitrate reacts with sodium acetate to give Lead acetate and sodium nitrate and all of these salts are soluble in water so no precipitate will be formed.
Pb(NO₃)₂(aq) + CH₃COONa(aq) → (CH₃COO)₂Pb(aq) + 2 NaNO₃(aq)

Answer 2

No precipitate forms in this reaction.

Step-by-step explanation:

It is an example of double displacement reaction.

In double displacement reaction, cations and anions of two salts interchange between themselves.

Here reaction between
`Pb(NO_(3))_(2)` and
`Na(CH_(3)COO)` forms
`Pb(CH_(3)COO)_(2)` and
`NaNO_(3)`.

Both
`Pb(CH_(3)COO)_(2)` and
`NaNO_(3)` are soluble in water. Hence no real precipitate forms in this reaction.

Balanced chemical equation:

`Pb(NO_(3))_(2)(aq.)+2Na(CH_(3)COO)(aq.)\rightarrow Pb(CH_(3)COO)_(2)(aq.)+2NaNO_(3)(aq.)`
