Web【解析】由于Ksp只与难溶电解质的性质和温度有关。而大多数电解质的Ksp随温度的升高而增大，但个别物质如Ca（OH）2，Ksp随温度的升高而降低。 3. 5℃时，在含有大 … WebTo obtain Ksp for PbI2, we must calculate [Pb2+] in each equilibrium system. This is most easily done by constructing an equilibrium table. We first find the initial amount of I- and Pb2+ ion in each system from the way the mixture were made up. Knowing I- and the formula of lead iodide allows us to calculate [Pb2+], Ksp then follows directly.
