Question

The equivalent conductivity of 0.1n ch3cooh at25c is80( and at infinite dilution 400.the degree of dissociation of acetic acid is

Answer 1

Degree of dissociation can be defined as a ratio of equivalence conductance at concentration c to the equivalence conductance at infinite dilution. That is it can be defined as follows:

$\alpha =\frac{\Lambda_{c} }{\Lambda _{00} }$  

Where,

$\alpha$ , is the degree of dissociation

$\Lambda_{c}$ , is the equivalence conductance at concentration c

$\Lambda _{00}$ , is the equivalence conductance at infinite dilution

$\Lambda_{c}$ , is given as 80

$\Lambda _{00}$ ,  is given as 400

So,  

$\alpha =\frac{80 }{400 }$  

$\alpha =0.2$
