Difference between reference electrode and indicator electrode?
Wiki User
∙ 10y ago
Often electrochemical studies are interested in one of the electrodes of the cell only.
The second electrode is present to complete the cell.
Electrode of interest is named working electrode or the indicator electrode; the
second electrode is know as reference electrode or auxiliary electrode (counter
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.
What is the basic technique or basic principle of amperometric titration?
The potential applied between the indicator electrode and the reference electrode is kept constant and the current through the electrolyte cell is then measured on addition of each increament oftitrating solution.
What is the difference between mono polar and bipolar electrode?
Monopolar electrode is single electrode measure voltage with respect to grond ,but bipolar electrode is two electrode measures the diff. voltage mainly bipolar is used inorder to get high Signal to Noise ratio.
What is the difference between a redox indicator and an acid-base indicator?
Redox doesn't use indicators. It uses the natural colouration of the chemicals involved to determine the endpoint and titre. Acid-base titrations use a pH indicator, as otherwise there is often no way to tell the difference between an acidic solution and a basic one.
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 the difference between external and internal indicator?
what is the difference between the external & internal indicator
What is the difference between a buffer and an indicator?
Distinguish between buffer and indicator
What is difference between standard hydrogen electrode and normal hydrogen electrode?
E(SCE)-E(H)=241 mV @25°C SHE is a primary standard electrode bt SCE is secondary reference electrode use for more easier work than SHE & SCE,s potential also measured by taking SHE as reference electrode.
What is the difference between a universal indicator and a pH meter?
A pH meter is an ion selective electrode (H+), it gives pH to a far more accurate figure and leaves no room for interpretation (based on wetness of strip, colour may appear to show different pHs with univ. indicator
What is Difference between internal and external indicators?
what is the difference between the external & internal indicator
What can increase the voltage difference between a metal electrode and a solution?
If electrons are left behind in metal this will increase the voltage difference between a metal electrode and a solution. Also if the solution becomes more positive this will cause an increase.
What is the difference between an area reference and a grid reference?
An area reference is a general location indicated on a map, such as a city or region, while a grid reference is a specific point identified by intersecting lines on a grid system, such as latitude and longitude coordinates or a military grid reference system (MGRS). Essentially, an area reference gives a broader location, while a grid reference pinpoints a precise position within that area.
What is the difference between mono polar and bipolar electrode?
Monopolar electrode is single electrode measure voltage with respect to grond ,but bipolar electrode is two electrode measures the diff. voltage mainly bipolar is used inorder to get high Signal to Noise ratio.

difference between acid base indicator and universal indicator
What can you cross reference for a champion rj2yle?
nothing, the difference between this plug and a rj19lm is minimal, but it has an extended electrode and a wide gap .040 instead of .030. You could theoretically use a 19lm with little issue but I wouldn't recommend it.
