H+ and Nations have ionic conductivities 349.8 and 50.11 Scmềmole-l respectively at infinite dilution. Calculate the ionic velocities of H+ and Nations in an electrolytic cellin which the electrodes are 5 cm apart and the applied potential is 2V.11 10.310 |
| Answer» E have u H + ∘ = Fλ H + ∘ = 96500349.8 =3.62×10 −3 cm 2 volt −1 s −1 u Na + ∘ = Fλ Na + ∘ = 9650050.11 =5.20×10 −4 cm 2 volt −1 s −1 Further, we KNOW that u ∘ = pot.diff.(volt)/distancebetweentheelectrodes(cm)ionicvelocity(cm/s) ∴ VELOCITY of H + =3.62×10 −3 × 52 =1.45×10 −3 CMS −1 Velocity of Na + =5.20×10 −4 × 52 =2.08×10 −4 cms −1 | |
