Final answer:
Strong organic bases form ionic salts with strong acids, while weaker bases like amines require weak acids for protonation. The ability of acids and bases to ionize and affect pH in aqueous solutions determines their strength.
Step-by-step explanation:
Strong organic bases form ionic salts easily when strong acids are added to a mixture. Conversely, weaker bases such as amines are only protonated by weak acids. This is reflective of the principle that the strength of an acid or base in aqueous solutions can be determined by their ionization constants. Strong acids dissociate almost 100% into ions when dissolved in water, whereas weak acids only partially ionize.
For instance, ammonia and pyridine, which are weaker bases, form ammonium chloride and pyridinium chloride, respectively, when reacted with HCl - a strong acid. The chloride ion from HCl does not react with water since it's a very weak base and thereby does not affect the pH significantly. However, the cations from the salts mentioned do react with water and can affect pH. It's important to understand that while ionic compounds are typically strong electrolytes, this does not directly correlate to their strength as acids or bases. The 'basicity' of a substance is more specifically related to its ability to produce OH- ions in water for bases, or H+ ions for acids, rather than just its electrolytic properties.
