Calculate molar conductivity of NH_4 OH at infinite dilution if molar conductivities of Ba ( OH )_2, BaCl_2 and NH_4 Cl at infinite dilution are 520,280, 129 ^-1 cm^2 mol^-1 respectively.

Question

Accepted Answer

Correct answer: A. (a) : _ Ba^2+^ +2 _ OH^-^ =520 ^-1 cm^2 mol^-1 _ Ba^2+^ +2 _ Cl^-^ =280 ^-1 cm^2 mol^-1 _ NH_4^+^ + _ Cl^-^ =129 ^-1 cm^2 mol^-1 By (i )2- ( ii )2+ (iii), we get _ NH_4^+^ + _ OH^-^ = 5202- 2802+129 =260-140+129=249 ^-1 cm^2 mol^-1

$Calculate molar conductivity of NH_{4} OH at infinite dilution if molar conductivities of Ba (OH)_{2}, BaCl_{2} and NH_{4} Cl at infinite dilution are 520,280, 129 Ω^{- 1} cm^{2} mol^{- 1} respectively.$
