Question

( The degree of dissociation of 0.1 M weak acid solution is 0.001. The ionisation constant of weak acid will be
(a) 10-5
(h) 10-6
(c) 10-7
(d) 10-8​

Answer 1

Answer:

the answer is 10-8 but the right answer is 10-9

Answer 2

D is the correct degree of the degree of dissociation of 0.1 M weak acid solution is 0.001.

 Meaning of disassociation- Dissociation is a mental state in which one disconnects from one's ideas, feelings, memories, or sense of self.

Professional therapy is required for dissociative disorders such as dissociative amnesia, dissociative fugue, depersonalisation disorder, and dissociative identity disorder.

Most mental health practitioners feel that prolonged childhood trauma is the root cause of dissociative disorders.

[H+]=Ka⋅C−−−−−−√

or=α2⋅C2−−−−−−√ [∴Ka=α2C]

=(10−3)2⋅(0.01)2−−−−−−−−−−−−−√

=10−5

pH=−log[H+]=−log10−5 =5

pOH=13−5=8
