The fourth homolog, butyric acid (CH3CH2CH2COOH), is one of the most foul-smelling substances imaginable. A salt is an ionic compound composed of a cation from a base and an anion from an acid. Reactions where at least one of the components is weak do not generally result in a neutral solution. Again, there will be other enthalpy changes involved apart from the simple formation of water from hydrogen ions and hydroxide ions. Propionic acid has three carbon atoms, so its formula is CH2CH2COOH. 2. An acid-base reaction is not the exchange of a hydrogen atom $\ce{H}$.It is the exchange of a hydrogen ion (or proton) $\ce{H+}$.Thus your answer should be: $$\ce{NH3(aq) +HNO3(aq) -> NH4+(aq) + NO3-(aq)}$$ The given answer combines the two ions produced into a single compound.
