^{how will i know when to take 1/2Ba or 2Cl.}

According to Kohlrausch’slaw. “conductivity of ions is constant at infinite dilution and it does not depend on nature of co-ions.”

For A_xB_y type electrolyte,

$A_xB_y \overset{H_2O}{\rightarrow} xA^+^y +YB^-^x$

$\lambda ^\infty _e_q = \frac{1}{z}\lambda ^\infty _B +\frac{1}{z^-}\lambda ^\infty _A$

Here Z⁺and Z^- are the charges present on cation and anion.

$\lambda ^\infty _m = m\lambda ^\infty _c +n\lambda ^\infty _a$

Here m and n are the number of moles of cations and anions
