Answer:
The answer of your question is......
Explanation:
The principle of a potentiometer is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length. The potentiometer is a simple device used to measure the electrical potentials (or compare the e.m.f of a cell)
Answer:
Potentiometric Titration principle of Potentiometry Principle. When the pair of electrodes are placed in the sample solution or analyte it shows the potential difference between two electrodes by addition of the titrant or by the change in the concentration of ions.
Precautions in use of Potentiometer
All high potential terminals of primary and secondary circuit should be connected at same point of Potentiometer.The known emf of primary circuit must be greater than the unknown potential difference to be measured in secondary circuit.The balancing length is always measured from the point of higher potential.
thank u very much for wishing me.☺
