True or False: A silver electrode cannot be used as an indicator electrode for Ag+ and...
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...
A silver-silver bromide wire is sometimes used as a reference electrode when Cl- -free conditions must be maintained. Write the cell notation and calculate the potential (at 30°C) of an Ag/AgBr reference electrode if it is immersed in a 3.5M solution of KBr. (Use concentrations, not activities in your calculation.)
A solution of K:Cr04 was titrated with AgNO, using a silver indicator electrode and a s.??. reference electrode. The product, Ag2Cr04, has a Ksp = 1.1 x 10-12. Eo-0.558 Then potential at the equivalence point would be 0.328 V Hint: 1. Use Ksp to calculate [Ag 2. Use Nernst equation 3. Decide which form is more available based on the pH 4. Do not forget Nernst equation
