Question

Identify the incorrect expression for solution of monoacidic base (BOH) [Kb is base dissociation constant of BOH and K, is hydrolysis constant of B*]​

Answer 1

Answer:

Explanation:

Base, BOH is dissociated as follows

BOH⇌B++OH−

So, the dissociation constant of BOH base

Kb=[B+][OH−][BOH]..........(i)

At equilibrium [B+]=[OH−]

∴Kb=[OH−]2[BOH]

Given that Kb=1.0×10−12

and [BOH]=0.01M

Thus, 1.0×10−12=[OH−]20.01

[OH−]2=1×10−14

[OH−]=1.0×10−7molL−1
