2. Estimate the diffusivity of KCl in a 1-M Table 3.7 Limiting Ionic Conductance in Water at 25C, in aqueous solution (infinite-dilution) at 25C. Hint: The infinite-dilution diffusivity in cm2/s of a salt in an aqueous solution can be estimated from the Nernst-Haskell equation: (DAB)=F2[(1/+)+(1/)]RT[(1+)+(1)] n. and n. are the valences of the cation and anion; +and are the limiting ionic conductance in (A/cm2)(V/cm)(g-equiv/ /cm3), with A in amps and V in volts; F is Faraday's constant 96,500 coulombs/g-equiv; T is temperature, K;R= gas constant =8.314J/(molK
