Electrodo de referencia de Hg/HgO para soluciones alcalinas ALS 013694.
The RE-61AP reference electrode is made of Hg/HgO
instead of calomel paste, and 1 M sodium hydroxide is used as an
electrolyte solution. It is used under high pH environment as reference
electrode.
HgO + H2O + 2e = Hg + 2OH- E0=118 mV vs RHE (25 deg C)
Potassium hydroxide solution can be used as a internal solution, instead of sodium hydroxide solution. The electrode holder is delivered empty, to be filled with 1 M NaOH aqueous solutions by the user.
