Round 8: 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. (10[1])Iodine-doped polyacetylene (“poly-acetyl-een”) has high values for this quantity due to its conjugated pi systems. The molar ionic form of this quantity is the product of drift velocity, Faraday’s constant, and charge and whose (10[1])SI units are siemens per meters. For 10 points, (10[1])name this quantity, the ability for an electrolyte solution to pass electricity. ■END■ (10[1])
