Why is graphite used as an electroed in dry cells?
Dry cell graphite electrode when treated with permanganate can be used as a hydrogen ion sensor. where activated dry cell graphite electrode seem to be suitable as potentiometric indicator electrodes. :)
Why is standard hydrogen electrode called reversible electrode?
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
What electrodes are used in conductometric titrations?
The platinum electrode is used in coductometry.
Can pencil lead be used as an electrode?
I am not sure what a electrode is, but I substituted a wire for pencil lead and it worked, but it didn't work as well as a wire
Which electrode is used in pH meter?
Combine electrod used in ph meter
What kind of material is used to make the positive electrode of a dry cell?
The positive electrode is a graphite rod (elemental carbon).

Why is standard hydrogen electrode called reversible electrode?
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
What is open circuit potential which is used to determine corrosion of materials?
The open circuit (oc) potential is the potential of the working electrode relative to the reference electrode when no potential or current is being applied to the cell.
If 500 electrons per second are being released at one electrode of an electrolytic cell then the number of electrons per second being used up at the other electrode is?
500 electrons per second, exactly.
Why is the positive electrode used up in electrolysis?
Thise electrode is the cathode.
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
What type of electrodes are used in potentiometric titration?
Potentiometric titration is a method to detect potential difference between the indicator electrode and reference electrode and thus determine concentration of chemical component, which reacts with reagent added to a solution potentially in equilibrium at the beginning.The popularly used reference electrode is either silver-silver chloride or mercury sulfate electrode, and the indicator electrode is generally made of glass electrode, platinum electrode and silver electrode or ion selective electrode.
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 do you call a tool that can be used to test for electrical conductivity?
It is a conductivity tester!
