What Is Difference Between Kf and Coulometer?

The main difference between the two is that with the volumetric method, the titrant

is added directly to the sample by a burette. Conversely, with the coulometric method, the titrant is generated electrochemically in the titration cell. The coulometric method measures water levels much lower than the volumetric method.

What is the use of coulometer?

The silver coulometer is a standard instrument used to determine the mass of silver deposited at a platinum cathode by the passage of an electric current through an aqueous silver nitrate solution. One coulomb (or ampere-second) of electricity is equivalent to 0.001 118 00 g of silver.

What is coulometric titration?

Coulometric titration is an absolute determination technique in which the mass of a given substance is determined by measuring the quantity of electricity required to electrolyze that substance; it does not necessarily require a standard solution. ... Thus the technique allows high-sensitivity measurements.
