What is meant by electrochemical series? Mention any two applications. 12. Discuss on the following: i) Metal - metal ion electrode Equation of the polarographic wave derived by applying_____ Beer-Lambert's law Nernst equation Ilkovic equation Planck's equation The diffusion current of Ba2+ion in a unknown solution found to be 18.0 µA. When 0.5 cm3of a 1.0 x 10-3M dm-3 solution of Ba+2 ions is added to 15cm3 of the unknown 3.692x 10 -5 mol dm-3 We can substitute this into Cottrell Equation i(t) = nFACD 1/2/ π t1/2 Giving the Ilkovich Equation: i d = 708nD1/2m2/3t1/6C I has units of Amps when D is in cm2s-1,m is in g/s and t is in seconds. C is in mol/cm3 This expression gives the current at the end of the drop life. The average The Kouteck^ correction to the Ilkovic equation Introduction An equation describing the limiting diffusion current at a dropping mercury electrode was obtained by iLKOViC1-2 and also by MACGILLAVRY AND RiDEA-L3. In the derivation, the diffusion layer was taken to be thin compared to the size of the drop. The Ilkovic equation is a relation used in polarography relating the diffusion current ( Id) and the concentration of the depolarizer ( c ), which is the substance reduced or oxidized at the dropping mercury electrode. The Ilkovic equation has the form where: polarization effects, Dipolar coupling, Me Conell equation and calculation of spin densities in inorganic radicals such as CO2- , CH 3 , BH 3- and F 2- . Spin orbit coupling and significance of g tensors. Zero field splitting and Kramer's degeneracy (fine structure), Applications Unit-III: Diffraction Techniques. (12 hrs) calibration are made. According to the Ilkovic equation, with all other factors constant, i d = kC. Where k is a constant defined by Ilkovic equation. This relation is the foundation of quantitative polarographic analysis and its general validity is well established. The results of polarographic determination of paracetamol from Ilkovic equation [21] for varying concentrations of the drug and was found to be 1.36 ± 0.04 (n = 5). The diffusion coefficient (D) of QTP was also calculated and was found to be 1.25 x 10-6 cm 2 s-1. This small value may be attributed to the bulky nature of the depolarizer. The results are shown in Table 2. Ilkovic equation [21] for varying concentrations of the drug and was fou
