ΛClCH2COONa∞=224Ω−1cm2gequiv−1\mathrm{\Lambda }_{\mathrm{ClC}{\mathrm{H}_2}\mathrm{COONa}}^\infty = 224{\Omega ^{ - 1}}{\kern 1pt} {\kern 1pt}\mathrm{c}{\mathrm{m}^2}{\kern 1pt} {\kern 1pt}\mathrm{g}{\kern 1pt} {\kern 1pt} \mathrm{equi}{\mathrm{v}^{ - 1}}
ΛNaCl∞=38.5Ω−1cm2gequiv−1\mathrm{\Lambda }_{NaCl}^\infty = 38.5{\Omega ^{ - 1}}{\kern 1pt} {\kern 1pt}\mathrm{c}{\mathrm{m}^2}{\kern 1pt} {\kern 1pt}\mathrm{g}{\kern 1pt} {\kern 1pt} \mathrm{equi}{\mathrm{v}^{ - 1}}
ΛHCl∞=203Ω−1cm2gequiv−1\mathrm{\Lambda }_{HCl}^\infty = 203{\Omega ^{ - 1}}{\kern 1pt} {\kern 1pt}\mathrm{c}{\mathrm{m}^2}{\kern 1pt} {\kern 1pt}\mathrm{g}{\kern 1pt} {\kern 1pt} \mathrm{equi}{\mathrm{v}^{ - 1}}
What is the value of λClCH2COOH=?{\lambda _{\mathrm{ClC}{\mathrm{H}_2}\mathrm{COOH}}} = ?
View answer and explanation
Correct option: C
388.5Ω−1cm2gequiv−1388.5{\Omega ^{ - 1}}{\kern 1pt} {\kern 1pt}\mathrm{c}{\mathrm{m}^2}{\kern 1pt} {\kern 1pt}\mathrm{g}{\kern 1pt} \mathrm{equi}{\mathrm{v}^{ - 1}}
Option C (388.5Ω−1cm2gequiv−1388.5{\Omega ^{ - 1}}{\kern 1pt} {\kern 1pt}\mathrm{c}{\mathrm{m}^2}{\kern 1pt} {\kern 1pt}\mathrm{g}{\kern 1pt} {\kern 1pt} \mathrm{equi}{\mathrm{v}^{ - 1}}) is correct because it applies Kohlrausch's law of independent migration of ions.
