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. (-5[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 (10[1])is the product of drift velocity, Faraday’s constant, and charge and whose SI units are siemens per meters. For 10 points, name this quantity, the ability for an electrolyte solution (10[2])to pass electricity. ■END■ (10[1])
