What is the difference between a weak and strong base? Only some of the molecules of a weak base dissociate to produce hydrogen ions when mixed with water, but all of the molecules of a strong base dissociate to produce hydrogen ions.

Solutions which can conduct electricity are called: homogeneous electrolytes polar metallytes
