Answer :
Balanced equations =
HCOOH + H₂O ⇒ HCOO¯ + H₃O⁺
Ka = [tex]\frac{[HCOO^+][H^+]}{HCOOH}[/tex]
What is Ka?
The acid dissociation constant determines the difference between strong and weak acids (Ka). The acid dissociates more as Ka increases. Strong acids must therefore dissociate more in water. A weak acid, on the other hand, is less likely to ionise and release a hydrogen ion, which results in a less acidic solution.
The acid dissociation constant, or Ka, is the equilibrium constant of an acid's dissociation reaction. This equilibrium constant serves as a numerical representation of the acidity of a solution. Ka is typically stated in units of mol/L.
