Round 10: Tossup 8

Excess Gibbs energy of systems containing these substances is calculated with binary interaction parameters in a model proposed by Chen and Evans. ITIES systems are named for acting as interfaces between two of these substances that are immiscible. (-5[1])Ostwald applied the law of mass action to determine these substances’ dissociation constant (-5[1])in his namesake dilution law. Kohlrausch’s law is used to calculate (10[1])a quantity of these substances, which Lars Onsager used to calculate their activity coefficients in his modification of Debye–Hückel (“duh-BYE HUCK-ull”) theory. (-5[2])While moving through these substances (10[1])in one device, (-5[1])lithium ions intercalate (10[1]-5[1])into (10[1])graphite at a solid (-5[1])interface. (10[2])Sulfuric acid acts (-5[1])as one (10[1])of these substances (-5[1])in lead–acid batteries. (10[1])For 10 points, name these substances that conduct (10[1])electricity (10[3])in (10[1])solution (10[1])through the movement of ions. ■END■ (10[6]0[6])

ANSWER: electrolytes [accept solid electrolytes or liquid electrolytes or strong electrolytes or weak electrolytes; accept interface between two immiscible electrolyte solutions; prompt on ionic solids or ionic liquids or ionic salts; prompt on dilute solutions until “solution” is read]
