Which is the salt bridge solutions must be used for silver chloride electrode?

Saturated KCl
Explanation: Saturated KCl is used as the salt bridge solution for silver/silver chloride electrode.

Which electrode would you use to detect chloride ion in a given sample?

The Chloride Ion-Selective Electrode (ISE) is used to measure the concentration of Chloride (Cl–) in aqueous samples. The concentration of the Chloride ion gives a quick measurement of salinity of water samples. Use the Chloride ISE to measure chloride levels in ocean saltwater or salt in food samples.

Which electrode is used as indicator electrode in potentiometric titration of agno3 against nacl?

Calomel and silver/silver-chloride electrodes are commonly used in potentiometric titration. In the case of possible interferences of chlorides (as in determination of halides), a mercurous sulfate electrode may be used. In the following series of experiments a home made Ag/AgCl/1 M KCl reference electrode is used.

What are the two electrodes used in the potentiometric titration?

Potentiometric Titration is done via the usage of two electrodes – an indicator electrode and a reference electrode (generally a hydrogen electrode or a silver chloride electrode).

Which substance is used as salt bridge in solution having soluble salts of silver mercury?

Contact with the measured solution is through a salt bridge of potassium chloride, the concentration of which may be 3.8 mol per liter or some other concentration appropriate to the application. Contact with the mercury is usually made by means of a platinum wire, which may be amalgamated.

Why Ag AgCl electrodes are used?

Quick and dirty answer: In order to transfer a charge from an electrode in a solution, you have to switch from electronic current (in the metal) to an ionic current in the solution (or vice versa). A Ag/AgCl electrode transfers the charge across its boundaries by a reversible Redox-Reaction.

What is a silver silver chloride electrode?

A silver chloride electrode is a type of reference electrode, commonly used in electrochemical measurements. ions as Ag metal onto the surface of the Ag wire). The reaction has been proven to obey these equations in solutions of pH values between 0 and 13.5.

Why salt bridge is used in potentiometric titration?

When the pair of electrodes are placed in the sample solution or analyte it shows the potential difference between two electrodes by addition of the titrant or by the change in the concentration of ions. A salt bridge is used to prevent interference of analyte with reference electrode.

Which electrode is used in potentiometer?

Reference electrodes generally used are hydrogen electrodes, calomel electrodes, and silver chloride electrodes. The indicator electrode forms an electrochemical half cell with the interested ions in the test solution. The reference electrode forms the other half cell.

Why reference electrode is necessary in potentiometric titration?

The indicator electrode forms an electrochemical half cell with the interested ions in the test solution. The reference electrode forms the other half cell. As the concentration of Mn+ changes, the Ecell changes correspondingly.

How do you measure AG+ concentration with a silver electrode?

A silver electrode can be used with a reference electrode to measure Ag+ concentration. The reaction at the Ag indicator electrode is The calomel reference half-cell reaction is The reference potential (E−, not E−o) is fixed at 0.241 V because the reference cell is saturated with KCl.

How do you find the concentration of silver chloride by titration?

Concentration by Titration (Mohr’s Method) Introduction This method determines the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added, a precipitate of silver chloride forms. Ag+ (aq) + Cl– (aq) → AgCl (s) The end point of the titration occurs when all the

What is the reference electrode for AG indicator electrodes?

Indicator Electrodes, 2. A silver electrode can be used with a reference electrode to measure Ag+ concentration. The reaction at the Ag indicator electrode is The calomel reference half-cell reaction is The reference potential (E−, not E−o) is fixed at 0.241 V because the reference cell is saturated with KCl.

How do you add dextrin to AgCl titration?

Add 5 mL of 2\% dextrin solution and 10 drops of 0.1\% dichlorofluorescein solution to the first flask. The purpose of the dextrin solution is to stabilize the colloidal suspension of AgCl(s) formed once the titration begins, and the dichlorofluorescein is the adsorption indicator.
