Question 2
Which of the following accurately describes the electrochemical principle of the chloridometer or chloride titrator?
A) The product of the potential difference produced in voltage along with the time in seconds required to reach an end point yields the number of coulombs, which is proportional to the quantity of analyte involved in the electrolysis.
B) The product of conductance produced in ohms along with the time in seconds required to reach an end point yields the number of coulombs, which is proportional to the quantity of analyte involved in the electrolysis.
C) The product of current produced in amperes along with the time in seconds required to reach an end point yields the number of coulombs, which is proportional to the quantity of analyte involved in the electrolysis.
D) The movement of chloride ions toward the anode and silver toward the cathode.
