is equal to ___________.


We can find the solution using Kohlrausch law of independent migration of ions. This law states that limiting molar conductivity of an electrolyte is equal to the sum of the individual limiting molar conductivities of the anion and cation of the electrolyte. There are three equations mentioned in the options which are acid-base neutralization reactions. They are –


HNO3 + NaOH NaNO3 + H2O


HCl + NaOH NaCl + H2O


HCl + NH4OH NH4Cl + H2O


Λom(H2O) = Λom(HNO3) + Λom(NaOH) – Λom(NaNO3)


Λom(H2O)om(HCl) + Λom(NaOH) – Λom(NaCl)


Λom(H2O)om(HCl) + Λom(NH4OH) – Λom(NH4Cl)


The correct options are (i), (iii) and (iv).
