The resistance of a solution 'A' is 50 ohms and that of solution 'B' is 100 ohms, both solutions being taken in the same conductivity cell. If equal volumes of solution A. and B are mixed, what will be the resistance of the mixture using the same cell. (Assume that there is no increase in the degree of dissociation of A and B on mixing.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
R = 66.67 ohms
Sol. R A = 50 Ω R B = 100 Ω
K A = 
& K B = 
when equal volmes one taken the
K resultant = 
= 
+ 
= 
R 1 = 
= 
= 66.7 Ω
