Question

acetic acid is 5% ionized in its dimolar solution. Calculate the dissociation constant of acid.
​

Answer 1

Explanation:

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
