what is the product of the reaction:
PbO + NaOH -> ???
or
PbO + NaOH + H2O -> ??
is there any difference?:frown:
thanks
Ok finally got latex how I wanted. It depends upon concentration of the base. Look up hydrolysis.
Excess Lead:
Pb(s) + 2OH^-(aq) \rightarrow Pb(OH)_2(s)
Excess NaOH:
Pb(OH)_2(s) + H2O(l) \rightarrow Pb(OH)_3^-(aq)
Lead (II) Oxide:
PbO(s) + H2O(l) + OH^-(aq) \rightarrow Pb(OH)_3^-(aq)
So if you use excess NaOH there will be no difference in your products.
Lead (IV) Oxide:
PbO2_(s) + 2H_2O(l) + 2OH^-(aq) \rightarrow Pb(OH)_6^{-2}(aq).
