Ammonia, nh3, is a weak base with a kb = 1.8 x 10-5. in a 0.8m solution of ammonia, which has a higher concentration: ammonia (nh3) or its conjugate acid the ammonium ion (nh4+)?
Since Kb is small the concentration of the products is less than the concentration of the reactants. Since ammonia is a reactant, it will have a higher concentration than NH4+, which is a product.
