Question

Which is working principal of conductometry ? *
(A) Measurement of potential.
(B) Measurement of conductivity of solution.
(C) Measurement of emf.
(D) None of the above

Answer 1

(B) Measurement of conductivity of solution.

Explanation:

• Conductometry may be a measurement of electrolytic conductivity to observe a progress of chemical change. Conductometry has notable application in analytical chemistry, where conductometric titration could be a standard technique made of pyrex or quartz and are fitted with two platinum electrodes.
• 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. It's notable applications in analytical chemistry.

Answer 2

Answer:

(B) Measurement of conductivity of a solution.

Explanation:

• Conductivity refers to the measurement of the electrical conductance of an aqueous electrolyte solution using a conductor.
• Its working principle is based on the electrical conductance of an aqueous electrolytic solution similar to that of a metallic conductor.
• It is the qualitative chemical analysis method to measure the conductivity of a chemical reaction.
• This conductivity at the initial stage is lowered due to the addition of the base. and after attaining equivalence, the concentration of ion increases.
• Conductometry has a notable application in analytical chemistry, where conductometric titration serves as a standard technique made of pyrex or quartz, which are fitted with two platinum electrodes.
• Conductometry is often employed to investigate ionic species and to observe a chemical reaction by studying the electrolytic conductivity of the reacting species or the resultant products.

Hence the working principle of conductometry is based on option (B)Measurement of the conductivity of the solution.
