Question

Limiting value of equivalent conductance of BaSO4
BaCl, and H2So4, are X, Y and Z respectively.
Equivalent conductance of HCl at infinite dilution is​

Answer 1

Limiting value of equivalent conductance of

• BaSO4 ⇒ X
• BaCl2 ⇒ Y
• H2SO4 ⇒ Z

from Kohlrausch's law,

equivalent conductance of an ionic compoundat infinite dilution is the sum of equivalent conductance of cations and anions present in that ionic compound.

so, $\Lambda^{\infty}BaSO_4=\Lambda^{\infty}Ba^+\Lambda^{\infty}SO_4^{--}$

$\Lambda^{\infty}BaCl_2=\Lambda^{\infty}Ba^+2\Lambda^{\infty}Cl^-$

$\Lambda^{\infty}H_2SO_4=2\Lambda^{\infty}H^++\Lambda^{\infty}SO_4^{--}$

so, $2\Lambda^{\infty}HCl=\Lambda^{\infty}BaCl_2+\Lambda^{\infty}H_2SO_4-\Lambda^{\infty}BaSO_4$

$2\Lambda^{\infty}HCl=Y+Z-X$

or, $\Lambda^{\infty}HCl=\frac{(Y+Z-X)}{2}$
