Justify the statement giving reason.

It is not possible to determine the moral conductivity of weak electrolyte at infinite dilution (Lambda_m^@) graphically by extrapolation. Calculate the molar conductivity of NH_4OH at infinite dilution if Lambda_m^@ of Ba(OH)_2,BaCl_2 and NH_4Cl are 523.4,280 and 130 ohm^(-1)cm^(-2)mol^(_1) respectively.

It is not possible to determine the molar conductivity of weak electrolyte at infinite dilution (Lambda_m^@) graphically by extrapolation. How can this problem be solved? Discuss the principle involved in the method.

The limiting molar conductivity of weak electrolyte can be calculated by using the law.

Assertion : Kohlrausch's law helps to find the molar conductivity of a weak electrolyte at infinite dilution. Reason: The cell potential of mercury cell is 1.35 V, which remains constant.

Is the effect of dilution on the molar conductance of strong and weak electrolytes the same?

Which of the following is/are true a.Specific conductance denotes conductances of 1cm^(3) of a substance b. Specific conductance as well as molar conductance of a solution of an electrolyte increases upon dilution. c. Limiting molar conductivity of a weak electrolyte cannot be determined by extrapolation of the plot of lamda_(m) against sqrt(c) d. Conductance of metals is by movement of free electrons

The molar conductivity of an electrolyte increases as Dilution increases Temperature decreases Dilution decreases None of these

With decreases in concentration of an electrolytic solution , Conductivity (K) decreases and molar conductivity (^^_m) increases. Limiting molar conductivity (^^_m^@) of a strong electrolyte can be determined by graphical extrapolation method, Suggest a method for the determination of limiting molar conductivity of a weak electrolyte, taking acetic acid (CH_3COOH) as example .

The molar conductance of M^(n +) = lamda_(x)^(oo) at infinite dilution and the molar conductance at infinite dilution of N^(m+) = lamda_(y)^(oo) . The equivalent conductance of the salt M_(m) N_(n) at infinite dilution will be (neglecting conductance due to water)

Assertion: According to Kohlrausch's law, the molar conductance of a strong electrolyte at infinite dilution is sum ofmolar conductivities of its ions. Reason: The current carried by cation and anion is always equal.
