Chapter 9: Q24P (page 209)

A 0.10 M solution of a base is 2.0% hydrolzed (伪=0.020)FindKb

Short Answer

Expert verified

The value of Kb=4.1脳10-5.

Step by step solution

01

Step : Consider a reaction

Let the given base be B.

The reaction of base B with water is as shown below:

B+H2O鈬�BH++OH-[B]=0.1-x[BH+]=[OH-]=x)

02

Calculation of the value of x

伪=xFx=伪脳F=0.02脳0.1=0.002

03

Calculate  

K=x30.1-x=0.00220.1-0.002=4.1脳10-5

Hence, the value of Kb is4.1脳105 .
