• B) K_sp = [Pb]² [C₂O₄]²
• C) \(K_{\mathrm{sp}}=\frac{\left[\mathrm{Pb}^{2+}\right]\left[\mathrm{C}_{2} \mathrm{O}_{4}^{2-}\right]}{\left[\mathrm{PbC}_{2} \mathrm{O}_{4}\right]}\)
• D) \(K_{\mathrm{sp}}=\frac{\left[\mathrm{Pb}^{2+}\right]\left[\mathrm{C}^{4+}\right]^{2}\left[\mathrm{O}^{2-}\right]^{4}}{\left[\mathrm{PbC}_{2} \mathrm{O}_{4}\right]}\)
• E) \(K_{\mathrm{sp}}=\left[\mathrm{Pb}^{2+}\right]\left[\mathrm{C}_{2}\right]\left[\mathrm{O}_{4}^{2-}\right]\)
