Write the balanced chemical equation for each of these reactions. Include phases. When aqueous sodium hydroxide is added to a solution containing lead(II) nitrate, a solid precipitate forms. However, when additional aqueous hydroxide is added the precipitate redissolves forming a soluble [Pb(OH)4]2–(aq) complex ion.

  1. 2NaOH(aq) + Pb(NO3)2(aq) ==> Pb(OH)2(s) + 2NaNO3(aq)

    Pb(OH)2(s) + 2NaOH(aq) ==> Na2Pb(OH)4(aq)

  7. The answer for the second equation input is

    Pb(OH)2 (s) + 2 NaOH^- (aq) --> [Pb(OH)4]^2- (aq) + 2 Na^+ (aq)

    This part of the problem annoyed the hell out of me before I actually got it.

  12. I can confirm Tamerra's answer.
    2NaOH(aq)+Pb(NO3)2(aq)--->Pb(OH)2(s)+2NaNO3(aq)

    Pb(OH)2(s)+2OH^-(aq)--->[Pb(OH)4]^2-(aq)

    is the correct answer on Sapling.
