Question

Calculate the solubility at 25°C of PbCIO, in pure water and in a 0.0090 M Na,C10solution. You'll find K, data in the ALEKS Data tab. Round both of your answers to 2 significant digits. solubility in pure water: solubility in 0.0090 M Na, CO solution: 0 X 5 ?

Answer 1

. Ksp of PbC04 = 2.8x1013 @ Solubility in Pure blater! Let solubility of Pb C004 = Smol PbCn04 - Fut? + Goo? s mallu smo smol/L.
