WebThe Ka value for acidic acid is equal to 1.8 times 10 to the negative fifth at 25 degrees Celsius. First, we need to write out the balanced equation showing the ionization of acidic acid. So acidic acid reacts with water to form the hydronium ion, H3O+, and acetate, which is the conjugate base to acidic acid. Web4.1.4. The Dissociation (Equilibrium) Constant, Ka: • The Ka refers to the Keq for the reaction where an acid donates a proton to water; • The Kb is the reaction in which a base accepts a proton from a water molecule. • The value of Ka or Kb is the strength of the acid or base. Large numbers are strong acids, small numbers are weak acids globo play app download computador
