See Section The interior cell is surrounded by an aqueous KCl solution, which acts as a salt bridge between the interior cell and the exterior solution. (b) In a glass electrode, an internal Ag/AgCl electrode is immersed in a 1 M HCl solution that is separated from the sample solution by a very thin glass membrane. Standard Electrode Potentials in Aqueous Solution at 25°C Cathode (Reduction) Half-Reaction: Standard Potential E ° (volts): Li + (aq) + e--> Li(s)-3.04: K + (aq Ag/AgCl reference electrode is a kind of commonly used reference electrodes.

0 = -0.95 - (0.0591 / 1) log K 0.95 / -0.0591 = log K log K = -16.07 K = 8.51 x 10¯ 17 The solubility product constant of AgCl is K sp = 1.8 × 10–10 M2. Using the relevant electrode potentials found on the data page, calculate the reduction potential at 298 K of a half-cell formed by: (a) an Ag electrode immersed in a saturated solution of AgCl. Marks 6 The standard electrode potential for Ag+(aq) + e- Ag(s) is E° = +0.80 V. 2011-12-31 · AG+ + Cl- -----> AgCl or Ag+ + 2Cl- -----> AgCl2 As doesn't ag have two elelctrons in its outter shell. And so two chlroines are needed to form a ionic bond. thanks alot. 銀－塩化銀電極を基準にして測定されたことを表すために、測定された電位の後ろに(vs.
