Why it is necessary to platinize the electrodes of a conductivity cellbefore it is used for conductance measurement?
The resistances of a series of aqueous NaCI solutions, formed by successive dilution of a sample, were measured in a cell with cell constant (the constant C in the relation κ = C/R) equal to 0.2063 cm-1. The following values were found: c/(mol dm-3) 0.00050 0.0010 0.0050 0.010 0.020 0.050R/Ω 3314 1669 342.1 172.5 89.08 3714(a) Verify that the molar conductivity follows the Kohlrausch law and find the limiting molar conductivity. (b) Determine the coefficient κ, (c) Use the value of κ (which should depend only on the nature, not the identity of the ions) and the information that λ(Na+) = 5.01 mS m2 mol-1 and , λ(I-) = 768 mS m2 mol-1, to predict (i) the molar conductivity, (ii) the conductivity,(iii) the resistance it would show in the cell, of 0.010 mol dm-3 Nal(aq) at 25 °C.
A sample of steel (0.506 g) was digested in acid and the solution made up to 100 cm3 with deionised water. Aliquots (25.0 cm3) of this solution were transferred into two volumetric flasks (100 cm3) labelled A and B. Flask A was made up to volume with deionised water. To flask B was added 10.0 cm3 of a 260 ppm standard solution of Mn2+ which was then also made up to volume with deionised water. The following absorbance results were obtained: Solution A = 0.356, Solution B = 0.578. Use these results to calculate the percentage (% w/w) of manganese in the steel sample.

Use the data in Table 19D.1 for the exchange-current density and transfer coefficient for the reaction Fe3+ + e− → Fe2+ on platinum at 25 °C to identify the current density needed to obtain an overpotential of 0.30 V as calculated (i) by using the Butler–Volmer equation, and (ii) by assuming that the current is entirely anodic. Comment on the validity of the latter assumption.
