The degree of dissociation of a weak monoprotic acid of concentration 1.2 x 10 -3 M having K a = 1.0 x 10 -4 is
Text Solution
Verified by ExpertsThe correct answer is:
D
25
By 
, as value of a is greater than 5% so we can not take assumptions and will have to use the exact formula.
So
will be given by:
