Question

Acetic acid is 5% ionised in its
decimolar solution. Calculate the
dissociation constant of acid

Answer 1

Answer:

Ionisation constant Ka = a² × c(1-a)

where a is the degree of dissociation

c is the concentration

Here a= 5% = 0.05

c = 0.1m

Substituting the values we get,  

Ka = 1.24 × 10⁻³
