What is the advantages of calomel electrode?
It cannot be used above 50 degree because the Hg2Cl2 breaks down,yielding an unstable readings. Mercurous chloride used in calomel electrode is a toxic substance
Why mercury placed at the bottom of calomel electrode?
because calomel act as a reference electrode
What is electrode potential of calomel electrode?
246 mV
Why calomel electrode dip into kcl solution after the use?
because that tip of the calomel electrode is made up of porous nature..If we keep it in environment, its get oxidised,,
Describe the construction of calomel electrode?
It consists of tube in the bottom of which is a layer of mercury ,over which is placed a paste of Hg+HgCl2.The remaining portion of cell is filled with a solution of normal or decinormal or saturated solution of KCl. a platinum wire dipping into the mercury layer is used for making electrical contact. the side tube is used for electrode is formulated as;Hg,Hg2Cl2,KCl. the electrode can be coupled with the hydrogen electrode of unknown pH.
What is a good substitute for a saturated calomel electrode?
For example, the silver/silver chloride electrode (without mercury).
Is Standard Calomel Electrode can act as cathode?
SCE can act as both anode and cathode according to the nature of other electrode.
Where can you buy saturated calomel reference electrode?
(UK) ACM, scimed, Sentek
What has the author Walter Fieldhouse Clarke written?
Walter Fieldhouse Clarke has written: 'I. A study of the hydrogen electrode, of the calomel electrode and of contact potential. II. A study of the ethylene electrode. III. Studies in oxidation and reduction ..' -- subject(s): Accessible book, Electrolysis
Advantages of the Standard electrode potential?
Standard electrode potential is a redox electrode. This is the forms the basis of the thermodynamic scale.
Can the saturated calomel reference electrode be used in strong alkaline media such as 2-5 N KOH solution?
No, Use a Mercury Oxide electrode in alkalai Media. Strong NaOH will damage glass. Available from Koslow Scientific Co.
What are the Advantages and dis advantages of stylus?
They cost extra.
