Q1

Plotting 1/Λm against cΛm for aqueous solution of a monobasic weak acid (HX) resulted in a straight line with y-axis intercept of P and slope of S. The ratio P⁄S is

[Λm = molar conductivity

\({\Lambda }_{\mathrm{m}}^{^\circ }=\)limiting molar conductivity

c = molar concentration

Ka = dissociation constant of HX]

a

\({\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}^{^\circ }\)

b

\({\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}^{^\circ }/2\)

c

\(2{\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}^{^\circ }\)

d

\(1/\left({\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}^{^\circ }\right)\)
