How do you find the molar conductivity of a coordination compound?
This question already has an answer here:
Molar conductivity is directly proportional to the number of ions on dissociation. If number of ions is same, the one with more net charge has more molar conductivity.
What is molar conductivity formula?
Solution: Molar conductivity = (1000 × k) /M. = (1000 × 0.023) / 0.30. = 76.66 cm² mol⁻¹ Molar conductivity of the KCl solution is 76.66 cm² mol⁻¹.
Which complex has highest molar conductivity?
Solution: [Co(NH3)6]Cl3 has highest molar conductivity.
What is the value of molar conductivity?
The term “specific conductance” is correctly defined as the electrical conductance of 1 cm³ of a solution at 25 °C. If the electrical conductance is measured at another temperature, the value is corrected to what it would be at 25 °C and reported as specific conductance at 25 °C.
Which of the following compound will have the lowest molar conductivity in solution?
Solution : The complex [`CoCl_(3)NH_(3)`] has the lowest molar conductance since it furnishes no ion in the aqueous solution.
Do coordination compounds conduct electricity?
Conductivity of coordination compounds refers to the degree to which a given coordination compound can conduct electricity. This property is different for different compounds.
What is the SI unit of molar conductivity?
siemens metres squared per mole
The SI unit of molar conductivity is siemens metres squared per mole (S m2 mol−1). However, values are often quoted in S cm2 mol−1.
What is the SI unit of conductivity?
The SI unit of electrical conductivity is siemens per metre (S/m).
What is the symbol of molar conductivity?
Molar conductance is defined as the conducting power of the dissolved ions produced in the solution. It is denoted by λ (lambda) and its unit is given by S cm2 mol–1.
Which will have greater molar conductivity and why?
Solution : Solution B will have greater molar conductivity because `wedge_(m)=kappaxxV`. With dilution, `kappa` decreases but V increases much more so that product increases.
Which of the following have maximum molar conductivity?
Final Answer: The molar conductivity of [Co(NH3)6]Cl3 is the highest.
Which has maximum conductance?
PtCl4⋅6NH3 has maximum conductance due to 6NH3, it forms the maximum number of ions in solution.
Why does molar conductivity increase with dilution?
As dissociation increases the number of ions increases and hence molar conductance increases with dilution.
How does molar conductivity vary with concentration?

What is the formula of kohlrausch law?
Kohlrausch’s law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations.
What is conductivity and molar conductivity?
Conductance is the reverse of electrical resistance; conductivity is the inverse of resistivity. Molar conductance is conductance of all the ions produced by ionization of 1 g mole of an electrolyte which is present in V mL of solution. Molar conductivity is conductivity of one mole of electrolyte.
What is specific and molar conductivity?
Specific conductance = Conductance × cell constant. Molar conductance: It is defined as the conductance due to 1 mol of the electrolyte present in volume V of the solution. For electrolyte concentration =c M.
What is resistivity formula?
See all related content → Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. The unit of resistance is the ohm.
What is the SI unit of resistance?
The SI unit of electric resistance is the ohm (Ω).
Is Ohm’s law is universal law?
No. Ohm’s law is not a universal law. This is because Ohm’s law is only applicable to ohmic conductors such as iron and copper but is not applicable to non-ohmic conductors such as semiconductors.
