Question
Calculate the value of Λm∞ for SrCl2 in water at 25oC from the following data :
Conc. (mol/lt) 0.25 1
Λm (Ω-1 cm2 mol-1) 260 250
Conc. (mol/lt) 0.25 1
Λm (Ω-1 cm2 mol-1) 260 250
Options
A.270
B.260
C.250
D.255
Solution
Λm = Λm∞ - b√c
260 = Λm∞ - 0.5 b ........ (1)
250 = Λm∞ - b ........ (2)
On solving (1) & (2), we get
Λm∞ - = 270 Ω-1 cm2 mol-1
260 = Λm∞ - 0.5 b ........ (1)
250 = Λm∞ - b ........ (2)
On solving (1) & (2), we get
Λm∞ - = 270 Ω-1 cm2 mol-1
