The mobility of the NH4+ ion is known is 7,623 x 10 ^-8 m2/Vs. Count:a. The molar conductivity of the NH4+ ionb. Ion velocity, when a voltage of 15 V is applied to the cell with separate electrodes 25 cm awayc. The transport number of NH4 + ions in CH3COONH4 solution if the ion is mobility CH3COO is 4.239 x 10-8 m2/Vsd. The amount of current carried by the NH4+ and CH3COO ions when the appliance set is connectedwith a coulometer I2 electrolyzed for 60 minutes as much as 50 mL. 10 mL of This solution was reacted with 20 mL of 0.05 M Na2S2O3 solution according to the following reaction:2S2O32- + I2 → S4O62- + 2I-
