Question

Write the chemical reaction for the ammonium ion in water, whose equilibrium constant is ka. include the physical states for each species.

Answer 1

The chemical reaction for the ammonium ion in water is:

NH4+(aq) + H2O(l) ----> H3O+ (aq) + NH3 (aq)  Ka = 5.60x10^-10

The ammonium ion NH4+ in aqueous form reacts with liquid water forming hydronium ion (aqueous) and aqueous ammonia, with a Ka of 5.60x10^-10.
