  • Specific Conductivity (K): It is the conductivity of 1 cubic-centimetre of a solution.
  • Equivalent Conductivity: It is the conductivity of a solution containing 1 equivalent of the solute between two parallel electrodes separated by 1 cm.

leq =

1000K

 S cm2 equivalent -1

 

N

  •  
  • Molar Conductivity: It is the conductivity of a solution containing 1 mole of a solute between two parallel electrodes separated by 1 cm.

lm =

1000K

  • Kohlrausch's Law : It states that the molar conductivity at infinite dilution of an electrolyte is equal to the sum of the molar conductivities at infinite dilution of the ions produced by the electrolyte.

  •  
  • Ohm's Law: It states that the strength of an electric current is directly proportional to the potential difference and inversely proportional to the resistance of the circuit.

V = IR

  • V is potential difference in volts
    I is current in ampere
    R is resistance in ohms
  • Degree of Ionisation: It is the extent of dissociation of an electrolyte.
  • Strong Electrolyte: An electrolyte that ionises completely in solution is called a strong electrolyte.
  • Weak Electrolyte: An electrolyte that ionises partially in solution is called a weak electrolyte.
  • Cell Constant: It is the ratio l/A for a conductivity cell where l is the distance between the electrodes and A is the area of the electrode.

Cell constant = 

l

 = K R

A

  •  
  • Battery: It is a combination of two or more galvanic cells electrically connected to work together to produce electric energy.
