A strong base produces more ions in a solution then a weak base
weak bases do not dissociate completely into their ions and they have a relatively low pH but for strong bases the condition is reversed
For weak base dissociation reactions, equilibrium lies further to the left than for strong bases.
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!
Strong bases dissociate or ionize completely. Weak bases dissociate or ionize only partially. The degree to which they ionize/dissociate is given by the Kb for each weak base.
If you are using the common English definitions of "strong" (meaning 'more') and "weak" (meaning 'less'), then a strong base will have a pH of 12-14 while a weak base will have a pH of 7-9. However, there is a specific scientific definition of 'strong' and 'weak' when used to describe acids and bases. In chemistry, a 'strong base' is a base that completely ionizes in water while a 'weak base' is a base that partially ionizes in water. If you are using these definitions, there is no way to categorically compare the pH of a strong base versus the pH of a weak base - the two variables do not related. Some strong (complete ionization) bases will have a lower pH (7-9) while other strong (complete ionization) bases will have a higher pH (12-14); the same is true of weak (partial ionization) bases.
Weak bases are soluble in water where as strong bases like KOH tend to heat up faster . Hence, strong bases are insoluble in water.
ionize
Yes. There are strong bases such as sodium hydroxide (NaOH) and weak bases such as ammonia (NH3)

Strong acids/bases will dissociate to almost 100% in water and their conjugate base/acid will be weak. Weak acid/base will not dissociate well in water and their conjugate base/acid will be strong.
No. Many strong electrolytes are bases or neutral salts.
in the strong-mayor system the mayor has strong executive power, and the weak-mayor system the mayors authority is limited

A strong acid ionizes partially in water while a weak acid ionizes fully in water.
yes
Weak bases are soluble in water where as strong bases like KOH tend to heat up faster . Hence, strong bases are insoluble in water.
