 ELECTRODES AND TYPES OF ELECTRODES

ELECTRODES 

Electrodes are materials which  is  a good conductor of electricity and chemical reaction 

TYPES OF ELECTRODES

1. Metal-Metal ion electrode

e  In this electrode a metal rod is immersed in its own salt solution  
   eg: Zn (znso4)  

2. Metal-metal insoluble salt electrode

    In this electrode, metal is coated by insoluble salt  and it is immersed in a solution containing a common   ion   
eg: calomel electrode   

3. Gas electrode 

    In this electrode, an inert metal is immersed in a solution containing ions of the gas is continuously bubbled through the solution
eg: Standard Hydrogen Electrode

4. Ion-selective electrode   

    It is a sensor that converts the concentration of a specific ion dissolved in a solution into an electric potential
 eg: Glass Electrode

5. Redox Electrode 

   In this electrode, an inert metal is immersed in a solution containing  ions of the substance in two oxidation state

GLASS ELECTRODE

-

 GLASS ELECTRODE It is a secondary reference electrode that produces a constant and reproducible electrode potential. It is an ion-selective electrode used with other reference electrodes to generate a potential difference. Construction It is made up of a special glass of relatively low melting point and high electrical conductivity, in the form of a sealed glass tube filled with 0.1M HCl, a platinum wire is inserted into it, to make electrical contact. The glass electrode is represented as Pt| 0.1M HCl | Glass | H+    The H+ ion concentration inside the electrode is constant. When the electrode is immersed into a solution of unknown H+, it becomes sensitive to the outside concentration in the solution. Such a sensitivity arises because of the difference between the H+ ion concentration inside and outside.       The electrode potential of the glass rod is : EG = EG0 + 0.0591 log [ H+ ]     EG = EG0 - 0.0591 pH  The glass electrode is used as the internal reference electrode for th

COLUMN CHROMATORGAPHY

 COLUMN CHROMATOGRAPHY It is a technique in which the stationary phase is solid or a liquid supported by a solid. When a column is used as the adsorbent it is called adsorption column chromatography. When the solid column is acting only as a support to the liquid adsorbent then it is called partition column chromatography. SEPARATION The selection of solvent is based on the nature of the components in the mixture. Adsorption depends upon the nature of the solvent and the adsorbent.  The rate at which the components of a mixture are separated depends upon the activity of the adsorbent and the polarity of the solvent. If the activity of the adsorbent is very high and polarity is low, then separation is low but gives good separation. If the activity of the adsorbent is low and the polarity of the solvent is high, then the separation is rapid but gives poor separation PROCEDURE A proper adsorbent is selected and made a slurry with a suitable liquid and placed in a suitable tube which is pl

 HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY It is a method used for the separation, purification, and identification of various nonvolatile high molecular weight organic compounds and natural products like cholesterol, terpenoids. ADVANTAGES High-speed separation Excellent column separation Solvent consumption is minimum Sensitive and accurate Separation can be done at an ambient temperature. PRINCIPLE The components of the mixture are separated depending upon the extent of adsorption and partition on the stationary phase and the rate at which the component is carried by the mobile phase. The mobile phase is liquid and the stationary phase can be solid or liquid. INSTRUMENTATION Solvent reservoirs are used to collect the different solvents. Pressure pump to apply pressure  Sample injector to give the mixture which is to be separated in the analytical column Regulator to adjust the flow rate Guard column to remove the particulate matter and contaminants from the solvent. The analytical colu
