Question #55e8d

Answer 1

`PbSO_4+2NH_4OH->Pb(OH)_2(s)+(NH_4)_2SO_4(aq)`

Explanation:

The partial reactions are:
`PbSO_4->Pb^(2+)(aq)+SO_4^(2-)(aq)`
`NH_3+H_2O->NH_4^+(aq) +OH^(-) (aq)` this one times 2
The net reaction is:
`Pb^(2+)(aq)+2OH^(-)(aq) ->Pb(OH)_2(s)`
The `NH_4^+` ions and the `SO_4^(2-)` ion are so-called spectator-ions.
