1. a.) A student mixes 47.0 mL of 3.30 M Pb(NO3)2(aq) with 20.0
mL of 0.00183 M Na2C2O4(aq). How many moles of PbC2O4(s)
precipitate from the resulting solution? What are the values of
[Pb2 ], [C2O42–], [NO3–], and [Na ] after the solution has reached
equilibrium at 25 °C? Ksp of PbC2O4 (s) is 8.5e^-9 M^2 b.) What are
the values of [Pb^2+], [C2O4^2-], [NO3^-], and [Na^+] after the
solution has reached equilibrium?
