I'M STUDYING THE IDEOMS THAT HAVE BUILT IN PARALLEL STRUCTURE, I ENCOUNTERED MISTAKE X FOR Y, WHICH DOESN'T MAKE SENSE
I NEED A DESCRIPTION AND EXAMPLE.

Kindly rephrase this sentence in a narrative manner
Procedure (Transference Number)Immerse the transference vessel up to approximately 2 cm below the lateral connecting tubes in the water-filled beaker. Measure the temperature during the reaction. Fix the U-tube to the support rod and fill it with 0.1 molar HNO3 up to external water level. After hanging the carbon electrodes in position, adjust the electrolyte level in the three legs of the U-tube to the same level. Subsequently, lower the transference vessel until the markings are submerged in the bath fluid to ensure sufficient temperature control. Weigh the anode and cathode of the coulometer and immersed them into a 250 mL beaker filled with H2SO4/ 0.5 molar CuSO4 solutions. Connect this coulometer, the transference vessel and the multirange meter in series with the connection cables. After the electric set up, perform electrolysis for 60 to 90 minutes at approximately 50 mA. The current intensity should be nearly constant. Measure the exact duration of the electrolysis procedure.
During this time, titrate 5 mL samples taken from the volumetric flask with 0.1 molar NaOH using methyl red as an indicator to check the initial concentration of the nitric acid.
After the electrolysis period, take 5 mL samples in the anode and cathode regions of the transference vessel while the electric field is still being applied as fast as possible and titrate those to determine the concentration. Quickly after it, interrupt the electric circuit and list the exact length of electrolysis period.
Carefully wash with water and acetone the copper electrodes of the coulometer, dry them in air, and weigh them to determine the mass exchange. After drying the transference vessel, determine the marked volume of the cathode and anode regions by filling them with water as a final step. The fluid displacement by the immersed electrodes is considered here.
