Weak acids only partially ionize to give hydrogen ions (H+)
weak bases only partially ionize to give hydroxide ions (OH-)
a strong base is a basic chemical compound that is able to deprotonate very weak acids in an acid-base reaction.
A strong base is strong because it dissociates 100%
This means it will have a very high Kb value.
Strong bases contain an alkali metal, Ca, Sr, or Ba hydroxides. All other bases that do not contain those elements are weak bases, such as NH3
Sodium hydroxide is a strong base; ammonia is a weak base.
In a chemical equation, weak acids and weak bases are usually recognizable by the _______.
Lowest pH, strong acids, then weak acids, then salts of strong acids and strong bases, then salts of weak acids and strong bases, then weak bases, then strong bases. All very confusing!
Because the conjugate bases are unstable the carboxylic acids are weak acids.

buffers
How strong or weak the acids or bases are.
No. Many strong electrolytes are bases or neutral salts.
Buffers.
Buffer systems. They convert strong acids or bases into weak acids or bases.
