Write the formula of calculating dissociation constant for weak electrolyte
Question
Write the formula of calculating dissociation constant for weak electrolyte
Solution
The dissociation constant for a weak electrolyte is calculated using the formula:
Ka = [A-][H+]/[HA]
Where:
- Ka is the acid dissociation constant
- [A-] is the concentration of the anion
- [H+] is the concentration of the hydrogen ion
- [HA] is the concentration of the undissociated acid
This formula is derived from the equilibrium expression for the dissociation of a weak acid. The concentrations are measured at equilibrium.
