Question

write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of lead(ii) acetate and zinc bromide are combined. be sure to specify states such as (aq) or (s). if a box is not needed leave it blank.

Explanation:

Step1: Write the balanced molecular equation

$Pb(C_2H_3O_2)_2(aq)+ZnBr_2(aq)
ightarrow PbBr_2(s)+Zn(C_2H_3O_2)_2(aq)$

Step2: Write the complete ionic equation

$Pb^{2 +}(aq)+2C_2H_3O_2^{-}(aq)+Zn^{2+}(aq)+2Br^{-}(aq)
ightarrow PbBr_2(s)+Zn^{2+}(aq)+2C_2H_3O_2^{-}(aq)$

Step3: Identify and cancel the spectator ions

Spectator ions are $Zn^{2+}$ and $C_2H_3O_2^{-}$.

Step4: Write the net - ionic equation

$Pb^{2+}(aq)+2Br^{-}(aq)
ightarrow PbBr_2(s)$

Answer:

$Pb^{2+}(aq)+2Br^{-}(aq)
ightarrow PbBr_2(s)$
