Find (in ) for in water at from the following data:
Conc. C (mol/L) = 0.04 and 0.25; ( ) = 208 and 190.
Fill your answer as the sum of digits (excluding decimal places) till you get a single digit answer.
Answer:
4
Solution:
Kohlrausch: = - A√(C). √(0.04) = 0.2 and √(0.25) = 0.5.
208 = - 0.2A and 190 = - 0.5A.
Subtract: 18 = 0.3A, so A = 60 and = 208 + 12 = 220.
Digit sum: 2 + 2 + 0 = 4.
Answer: 220 (OMR answer 4).
