4. The Solvents System
Consider any solvent which undergoes self-ionization:
Acids are substances that increase the concentration of the
positive ions characteristic of the solvent, and bases are
substances which increase the concentration of the negative
ions characteristic of the solvent. thus in water, substances
providing protons are acids, and substances poviding hydroxyl
ions are bases. similarly in liquid ammonia, ammonium salts are
+
acids since they provide NH ions, and sodamide NaNH is a
2
4
+
base since it provides NH ions. In N O as solvent, NOCl is an
2
2 4
acid and NaNO is a base. Clearly this definition applies equally
3
well to proton and non-proton systems.
