Ammonia, NH3, is a weak base with a Kb value of 1.8 times 10-5. 1. What is the pH of a 0.305 M ammonia solution? 2. What is the percent ionization of ammonia at this concentration? Express your answer What would be the pH of a 0.563 M so...
Ammonium (NH4+) is a positively charged ion (or cation) that is formed by the addition of a hydrogen proton to ammonia (NH3). Ammonia is found naturally in water, but if it is found at higher than natural levels this is a sign of contamination. This is why it’s so important to te...
Ammonium in solution is in equilibrium with ammonia, which acts like a Brønsted-Lowry base, according to the reaction: H30+ + NH3 < - > NH4+ + H2O. The NH3gas crosses the cell membranes, and once within the cytosol regenerates NH4+, thereby reducing the concentration ...
