Conductivity of an Electrolyte solution is measured of its ability to conduct electricity. 

The SI unit of electrical conductivity is siemens per metre (S/m). 

Conductivity

Conductivity of river water is high as compared to sea water ( everything depend on ions ) 

There are Three Types of conductivity : 

  1. Table type conductivity
  2. Flow type conductivity
  3. Pipette type conductivity 

Important Questions from Ma'am : 

  1. What is the relation between conductivity and total dissolve solid.
  2. Derive the equation to find specific conducterts it's cell constant.
  3. Explain principle of conductivity explain the components and working with neat sketch.
  4. List different types of conductivity cells depend on their use.
  5. Highlight the significance of conductivity in water and  wastewater. 

Potentiometry 

Is the technique that is used analytical chemical usually to find the concentration of solute in solution.

  1. Metal metal ion Electrode (Ag/ag+)
  2. Metal metal salt Electrode (Ag/Agcl+)
  3. Oxidation Reduction Electrode ( Fe+2/Fe+3)
  4. Metal metal amalgon (Hg/ Hg2cl2)
  5. Gas electrode ( PT/H2 )
Potentiometry

There are Two Types of Potentiometry instruments are used : 

  1. Ion selective method ( alkali, fluorine, fluoride, inert measurement ) 
  2. pH meter Method

Membrane

There are 5 types of Membrane : 

  1. Ion exchange membrane
  2. Polymeter membrane
  3. Cellulose membrane
  4. Glass membrane

Important Questions from Ma'am:

  1. Define potentiometry
  2. Explain the principle of an selective electrode
  3. List different types of electrode used in electrical method of measurement briefly explain with figure.
  4. List different membrane used in measuring electrode.
  5. What is reference electrode explain.
  6. Explain standard celonometer with figure.
