I mentioned that $\ce{CH3CH2NH2}$ is weak, meaning that this reaction is reversible: $$\ce{CH3CH2NH2 + H2O <=> CH3CH2NH3+ + OH-}\tag1$$. This means that they are not very basic and can only be used in certain types of applications. Although the number of hydrogen ions in a liter of pure water is large on the scale of what we usually think about (in the quadrillions), the number of total water molecules in a liter dissociated and undissociated is about 33,460,000,000,000,000,000,000,000, Solutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water.
