Question

The degree of dissociation constant for a solution is 0.02 . Calculate dissociation constant for 5 molar solution​

Answer 1

Answer:

Degree of Dissociation

The degree of dissociation (α) for weak acids and bases is defined as the fraction of 1 mole that dissociates at equilibrium.

AcOH⇆AcO−+H+ Initial point:1mole00 Equilibrium:1-ααα Ka=

c2α2

c(1−α)

=

cα2

1−α

If there are c moles:c(1-α)cαcα

By definition, α is a unit factor but it is often also expressed as a percentage.
