Question

Q.17)
Sensitivity of galvanometer in amperometric titration
indicates value of (1 marks)
Ans.
Residual current
Diffusion current
Limiting current
Reference current​

Answer 1

The second Option, Diffusion current is the value of the galvanometer in amperometric titration.        

• Based on the electric current produced during the titration, determining the endpoint is termed amperometric titration.
• WIth the help of an instrument named galvanometer the produced current's quantity is measured.
• The movement of charge carriers causes the diffusion current.
• The diffusion current and electro-active material in the solution depend on each other.
• The galvanometer shows the diffusion current.

Answer 2

Sensitivity of galvanometer in amperometric titration indicates value of Residual current.

• Amperiometric tiration is the standard method used for the comaprison of accuracy and in determining the residual chlorine in the drinking water.
• Second option is diffusion current which is directly propotional to the concentration of electro active material present in the solution.
• Diffusion current is plotted versus the volume of the titrant to give a titration curve.
