The common ion effect can be applied to a solution of lead thiocyanate when potassium thiocyanate is added. Since there is a common ion, the cyanate ion, the molar solubility of lead thiocyanate goes down in the presence of potassium thiocyanate Calculate the molar solubility of lead thiocyanate in 0.500 M KSCN Express your answer with the appropriate units. Lead thiocyanate, Pb(SCN)2, has a Ksp value of 2.00 x 10 5

Why can a silver electrode be used as an indicator electrode for Ag^+ and halides? The silver electrode contains two membranes. One membrane contains a substance that reacts with Ag^+ and halides to form an ionic silver-halide complex. The potential difference created at the second, ion-selective membrane changes as the [silver-halide complex] changes. Because Ag^+ and halides equilibrate with ion-exchange sites at the outer surface of the ion-selective membrane. Diffusion of Ag^+ and halides out of the membrane creates a...
