I have been having trouble coming up for the reaction for the addition of HNO3 to solid Pb(OH)2.  From my observations, when in acidic solution, the precipitate dissolves, which it does not in basic solution (made basic with NH3 not NaOH--in which case it dissolves without the addition of HNO3).  Any tips?  Thanks!

All nitrates are soluble. Therefore, that reaction with a acid and base produces a soluble salt and water. ex. 2HNO3(aq) +Pb(OH)2(aq)--PB(NO3)2(aq) +2H2O(l). As a result, there should be no precipitate produced in this reaction. Solid lead hydroxide should dissolve in nitric acid. That's not the case with bases because they are both reducing agents, ion exchange might occur in this instance depending on the electronegativity of the other base.
