Does ammonia act as a weak base in aqueous solution?
Ammonia (NH3) acts as a weak base in aqueous solution. What is the acid that reacts with this base when ammonia is dissolved in water? none, there are no acids in pure water H2O NH4+
Does ammonia act as a base oxygen in pure water?
none, there are no acids in pure water H2O NH4+ trick question, because no acids are present, ammonia cannot act as a base oxygen that always is dissolved in water 12. The base ionization constant Kb describes which of the following reactions for a weak base, B, in aqueous solution?
What is the Kb value of a solution of ammonia?
The Kb value for ammonia is 1.8 × 10–5. 1.9 × 10–3 M 4.2 × 10–4 M 41. What is the pOH of a 0.20 4.44 4.74 0.70 solution of ammonia? The Kb value for ammonia is 1.8 × 10–5 2.72 3.38 42. What is the pH of a 0.20 9.56 9.26 4.74 solution of ammonia? The Kb value for ammonia is 1.8 × 10–5 11.28 2.72 43.
