Answer:
Lead (II) sulphate, [tex]PbSO_4_{(s)}[/tex]
Explanation:
A precipitate reaction is one involving two aqueous reactants in which one of the products is a solid or a precipitate. It can also be defined as a reaction involving the formation of insoluble salt from mixture of two soluble salts.
The equation of reaction involving [tex]K_2SO_4_{(aq)}[/tex] and [tex]Pb(NO_3)_2_{(aq)}[/tex] is as follows:
[tex]K_2SO_4_{(aq)} + Pb(NO_3)_2_{(aq)} ---> PbSO_4_{(s)} + 2KNO_3_{(aq)}[/tex]
The precipitate formed in this case is [tex]PbSO_4_{(s)}[/tex] because it is the only insoluble one of the two products.
Hence the white color precipitate that forms is [tex]PbSO_4_{(s)}[/tex]
