Transport Number of H+

What is the transport number of H+?

Based on the given data, what is the transport number of H+?

Answer:

The transport number of H+ is 0.823.

In the given scenario, a Hittorf cell fitted with Ag/AgCl electrodes was filled with 0.0106 molal aqueous HCl. A current of 2.00 mA was passed through the cell for 10800 seconds. After the electrolysis, the weight of the cathode solution was found to be 51.7436 grams, with 0.0267 grams of HCl present in the cathode solution. We need to determine the transport number of H+ in this electrolytic cell.

First, we calculate the amount of HCl initially present in the solution before electrolysis. Then, we determine the amount of HCl gained during the electrolysis process. By comparing the moles of H+ gained to the moles of Cl- gained, we can find the transport number of H+.

Through the calculations, we find that the transport number of H+ in this specific electrolytic cell setup is 0.823. This value indicates the efficiency of the transport of H+ ions compared to Cl- ions during the electrolysis process. A higher transport number suggests a higher selectivity for the transportation of H+ ions.
