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...

Q7) A 1.23 g sample, which contains gold (Au), silver (Ag) and metal oxides, is treated with concentrated nitric acid (HNO;), which dissolves all the metals and metal oxides with the exception of the gold. The mass of yellow metal remaining is 7.4 x 10 g. The solution is then treated with aqueous sodium chloride (NaCI), which precipitates silver chloride (AgCI) and nothing else. A total of 0.196 g of AgCl is obtained. What is the percent gold and silver...
