Web(d) State and explain Kohlrausch’s law of independent migration of ions. Why does the conductivity of a solution decrease with dilution? 2+1=3 (e) An aqueous solution of CuSO4 was electrolyzed between platinum electrodes using a current of 0·1287 ampere for 50 minutes. (Atomic mass of Cu = 63·5 g mol–1) (i) Write the cathodic reaction ... WebIn the case of weak electrolytes, we use the Kohlrausch law of ion migration to determine the limiting conductivity on an independent basis. The Kohlrausch law formula can be used to determine the molar conductivity of a weak electrolyte, as well as to determine the dissociation constant and restrict the conductivity of the electrolyte.

WebApr 11, 2024 · There is a simple demonstration of Kohlrausch's law. Start with four electrolytes with common ions, say AX, AY, BX and BY. The law says that the difference in limiting molar conductivities of two salts with a common ion is independent of that ion, for instance: $$\Lambda_m^\circ (\ce{AX})-\Lambda_m^\circ (\ce{AY})=\Lambda_m^\circ … Webaccording to Kohlraush’s law of Independent migration of ions - the molar conductivity at infinite dilution of an electrolyte is equal to the same of molar conductance term multiplied by the number of respective ion present in the formula unit of the electrolyte. If λ+ ∞and λ- ∞respective represent the molar conductivities of cations and anions of an electrolyte, … merino wrap sweater

WebNov 2, 2024 · Kohlrausch law of independent migration of ions: The law states that limiting molar conductivity of an electrolyte can be represented by the sum of the individual contributions of the anion and cation of the electrolyte. On dilution, the conductivity (k) of the electrolyte decreases as the number of ions per unit volume of solution decreases. WebJun 14, 2024 · Kohlrausch Law of Independent Migration of Ions: The limiting molar conductivity of an electrolyte is equal to the sum of the individual contributions of the anion and cation of the electrolyte. If λ°(Na+) and λ°(Cl-) are the limiting molar conductivities of sodium and chloride ions, then limiting molar conductivity of NaCl is: merino wrist warmers buttons
