EC or Electrical Conductivity Represents the Ionic Strength of a Solution to Conduct Electricity. Ions Carry Out the Action of Electricity Transfer in Materials. If the Concentration of Ions in the Solution is High, the Electricity Will Transfer Better. In Fact, If the Value of EC is Higher, More Electricity Will Transfer.
Chemical Substances that Produce Ions in Aqueous Environment Are Called Electrolytes. Electrolyte Temperature is One of the Effective Factors in Electrical Conductivity. Because as a Result of Increasing the Temperature at a Certain Potential, the Atoms, Molecules and Ions of the Solution Will Have More Mobility, which Ultimately Increases the Electrical Conductivity of the Solution. Since the Conductivity Depends on the Temperature, the Temperature Compensator is Used to Correct the Error Caused by the Temperature. Also, the Degree of Ionization of the Electrolyte, the Migration Speed of Different Ions, the Temperature of the Electrolyte and the Concentration of the Electrolyte Are Effective Factors in Electrical Conductivity.
In EC Measurement Using a Conducting Electrode, Two Plates with an Area of A at a Distance of D from Each Other Are Used, which Play the Role of Anode and Cathode. The Cell Constant is Obtained Through the Following Equation:
TDS Means Total Solid Impurities in Water, which Represents the Sum of All Ions in Water. Electrical Conductivity and the Presence of Total Solids (TDS) Do Not Have a One-to-One Relationship. But in Dilute Solutions (Such as Natural Water), the Relationship Between These Two Factors is as Follows:
TDS = 0.5 EC
The Relationship Between TDS and EC for Samples is Different According to Its Chemical and Physical Characteristics.
