Round 9: Tossup 19

On a Walden plot, the logarithms of this quantity and inverse viscosity vary linearly for an ideal potassium chloride solution. This quantity is increased by tetrathiafulvene (“tetra-thia-fulvene”) complexing with a para-quinone derivative containing four cyano groups. Lars Onsager devised a “limiting” form of this quantity that is calculated using concentration and Kohlrausch coefficients. This quantity is measured to obtain estimates for total dissolved solids in water tests. Iodine-doped polyacetylene (“poly-acetyl-een”) has high values for this quantity due to its conjugated pi systems. (-5[2])The molar ionic form of this quantity is the product of drift velocity, Faraday’s constant, and charge and whose SI units are siemens per meters. (-5[1])For 10 points, name (10[1])this quantity, the ability for an electrolyte (10[2])solution to pass electricity. (10[1])■END■ (10[3]0[1])
