A salt is formed when a strong acid reacts with a strong base. acid base conjugate base conjugate acid. In this case, the involved conjugate acids are NH4+ and CH3NH3+. Ex: HSO4−, for example, can donate H+ to become SO42− (acting as an acid), or it can accept H+ to become H2SO4 (acting as a base): p K a of acetic acid = 4. CH3NH3 and NH3 are two different compounds therefore they act differently. 0 Answers/Comments. Postby AlexisRobles3D » Thu Dec 11, 2014 11:40 pm. The production of hydroxide ions on dissolving in an aqueous solution shows the basic nature of CH 3 NH 2. Its anion, NO3-, has virtually no tendency to accept protons in dilute solutions. Here are a few examples A compound that can donate protons are considered acids but here in Methanol; as a result, water is a better proton donor, which makes Methanol a weak acid. CH3NH3+ Remember the positive charge!!! Later, we extended the definition of an acid or a base using the more general definition proposed in 1923 by the Danish chemist Johannes Brønsted and the English chemist Thomas Lowry.
