What is the principle of conductometric titration?
What is the principle of conductometric titration?
The principle of conductometric titration is based on the fact that during the titration, one of the ions is replaced by the other and invariably these two ions differ in the ionic conductivity with the result that conductivity of the solution varies during the course of titration.
What is conductometric titration explain with example?
Titration. Conductometric titration is a type of titration in which the electrolytic conductivity of the reaction mixture is continuously monitored as one reactant is added. The equivalence point is the point at which the conductivity undergoes a sudden change.
What are the types of conductometric titration?
Types of conductometric titrations:
- Acid-base titration.
- Precipitation titration.
- Replacement titration.
- Redox (oxidation-reduction) titration.
- Complexometric titration.
Which is working principle of Conductometry measurement of conductivity?
The working principle of conductometric titration is measurement the conductivity of the solution. Conductometry is employed to investigate ionic species and to observe a reaction by studying the electrolytic conductivity of the reacting species or the resultant products.
Which instrument is used in conductometric titration?
INSTRUMENTATION OF CONDUCTOMETER :- Current source :- Alternative current source is used. High frequency alternating current generator is employed. electrical potential is applied ions will be transfer and ultimately conductance take place. Conductivity meter :- Digital display, calibrator,power switch.
Which electrode is used in Conductometry?
Answer: Conductivity cell :- Made of pyrex or quartz and are fitted with two platinum electrodes. Should be placed in vessel containing water to maintain constant temp. types of conductivity cells are TYPE-A, TYPE-B, & TYPE-C.
Which electrode is used in conductometric titration?
Explanation: Conductometry is a process in which two electrodes are used to measure all electroactive compounds in a solution. In this, Platinum sheets are used.
What is the unit of Conductometry?
Conductometry is the measurement of the electrical conductivity of a solution. The conductance is defined as the current flow through the conductor. In other words, it is defined as the reciprocal of the resistance. The unit for the conductance is Seimens (S) which is the reciprocal of Ohm’s (Ω −1).
What is the unit of conductance?
siemens (S), unit of electrical conductance. In the case of direct current (DC), the conductance in siemens is the reciprocal of the resistance in ohms (S = amperes per volts); in the case of alternating current (AC), it is the reciprocal of the impedance in ohms.
Which cell is used in Conductometry?
The two electrode cell is the most commonly used conductivity cell Glass cells have electrodes made of platinum. Epoxy cells have easy to clean graphite plates….Conductivity Cells.

What is conductance formula?
Conductance is the opposite of resistance: the measure of how easy it is for electric current to flow through something. Conductance is symbolized with the letter “G” and is measured in units of mhos or Siemens. Mathematically, conductance equals the reciprocal of resistance: G = 1/R.
What is siemens SI unit?
The siemens (symbolized S) is the Standard International (SI) unit of electrical conductance. The archaic term for this unit is the mho (ohm spelled backwards). Siemens are also used, when multiplied by imaginary numbers, to denote susceptance in alternating current (AC) and radio frequency (RF) applications.
What is SI unit of conductance?
The siemens (symbolized S) is the Standard International (SI) unit of electrical conductance. The archaic term for this unit is the mho.
What is the symbol of conductance?
letter G
In equations, an uppercase letter G symbolizes conductance. The standard unit of conductance is siemens (S), formerly known as mho. Conductance is essentially a property found in good conductors of electricity, like aluminum and copper.
What is mho and ohm?
Medical Definition of mho : a unit of conductance equal to the reciprocal of the ohm : siemens.
What is SI unit of conductivity?
The SI unit of conductivity is Siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of measuring the ionic content in a solution.
What is the formula of mho?
The mho is a unit of electrical conductance and is the reciprocal of the resistance in ohms, and is actually ohm spelled backwards. One mho is equal to one siemens, which is the SI derived unit of conductance. Mhos can be abbreviated as ℧; for example, 1 mho can be written as 1 ℧.
What is the difference between conductance and conductivity?
Conductance is the extrinsic property, whereas the inherent property is conductivity. This suggests that conductance is an object’s property depending on its quantity/mass or physical form and scale, whereas conductivity is the object’s intrinsic property of the substance.
